Speech Title: Control Issues in Active Magnetic Suspension Technology

Abstract:The noncontact suspension of an object is still fascinating people. A typical method of achieving such suspension is magnetic suspension in which the object (floator) is kept in air by magnetic force. There is no contact between stator and floator. No mechanical friction and wear are expected during operation even without lubrication. These advantages have already given rise to many industrial applications such as Maglev systems for transportation, and magnetic bearings for the suspension of rotating object (rotor).

Among various methods of magnetic suspension, active electromagnetic suspension is most widely used in industrial applications. In this technology, active control plays a critical role mainly because this type of magnetic suspension system is inherently unstable.

In this speech, several approaches of control are introduced. First, an overview of technological fundamentals is explained. Then, the pioneer and/or recent works of the author are presented.

Speech Title: The Developing South Asia in view of Global Energy Crunch

Abstract: The economic prosperity and energy security for South Asia’s 1.9 billion people are in severe jeopardy due to the global energy crisis created by the western sanctions on Russia’s energy resources export to the world market. The economic setback has been intensified further by the aftermath of COVID-19 pandemic, skyrocketing global energy price, high-inflation, and national currency devaluation. All energy importing developing nations including South Asian energy deficient Bangladesh, India, Pakistan, and Sri Lanka have been forced to pause energy import, causing unprecedented energy shortages for power generation, industrial and fertiliser outputs, and other economic and commercial activities. The country-wide power blackout and power rationing have caused unceremonious impact on all aspects of economic, social, education, health, and cultural life. This paper highlights the impact of the energy crisis in developing nations with reference to South Asia, the home of 215 million extreme poor people who live below the poverty line (2.15 US dollar per person per day). The paper also emphasises on the needs for enhanced energy security and optimal utilisation of indigenous energy resources.

Speech Title: Future Perspective of Carbon-Free Hydrogen/Ammonia in Energy System

Abstract: The utilization of carbon-based fuels has led to the massive emission of greenhouse gases, especially CO2, to the atmosphere. Furthermore, energy security, energy equity, and environmental sustainability are the important pillars toward the realization of sustainability in energy system. In order to strengthen these pillars and solve the environmental problems, clean and renewable energy sources have been gradually deployed, along with the adoption of carbon- free secondary energy sources. As non-carbon based chemical and secondary energy source, hydrogen is believed to play important roles in the future energy system due to its excellent characteristics of high conversion efficiency, cleanliness, and technological advancements. However, currently hydrogen faces several challenges, especially related to its storage/transportation and economic performance. Several promising hydrogen storage technologies are analyzed and compared, including liquid hydrogen, ammonia, and liquid hydride. Ammonia is considered promising option for hydrogen storage due to its higher total energy efficiency, infrastructure readiness, and economic performance. Furthermore, in order to improve the overall economic performance of hydrogen, a scenario to facilitate its possible massive utilization in the existing energy systems must be provided. Hence, hydrogen can have broader options, including as raw fuel for base-load power generation, chemical fuels, and adjusting/balancing services.

Speech Title: The X-Structure/Mechanism Approach to Beneficial Nonlinear Design in Engineering

Abstract: Nonlinearity can take an important and critical role in engineering systems and thus cannot be simply ignored in structural design, dynamic response analysis, and parameter selection. A key issue is how to analyze and design potential nonlinearities introduced to or inherent in a system of under study. This is a must-do task in many practical applications involving vibration control, energy harvesting, sensor systems and robots etc. This paper presents an up-to-date review on a cutting-edge method for nonlinearity manipulation and employment developed in recent several years, named as the X-shaped structure or mechanism approach. The method is inspired from animal leg/limb skeletons and can provide passive low-cost high-efficiency adjustable and beneficial nonlinear stiffness (high static & ultra-low dynamic), nonlinear damping (dependent on resonant frequency and vibration excitation amplitude) and nonlinear inertia (low static & high dynamic) individually or simultaneously. The X-shaped structure or mechanism is a generic structure or mechanism representing a class of beneficial geometric nonlinearity with realizable and flexible linkage mechanism or structural design of different variants or forms (quadrilateral, diamond, polygon, K/Z/S/V-shape, or others) which all share similar geometric nonlinearity and thus similar nonlinear stiffness/damping properties, flexible in design and easy to implement. This paper systematically reviews the research background & motivation, essential bio-inspired ideas, advantages of this novel method, beneficial nonlinear properties in stiffness, damping and inertia, and potential applications, and ends with some remarks and conclusions.

Speech Title: Hydrodynamics of aquatic animal swimming

Abstract:“How does a fish swim?’ is essentially a fascinating question. For hundreds of millions of years, adaptation and evolution have enabled fish to achieve excellent propulsion performance with their fast speed and high efficiency. During this long history of evolution, swimming animals have mastered an exquisite capacity to control their body and the flow around themselves to efficiently cruise in water. The distinctive swimming abilities of fish have inspired scientists and engineers to analyze locomotive mechanisms and to design fish-like robots. There is no doubt that human beings admire the swimming skills of aquatic animals and hope to have a similar capacity. With the development of science and technology, researchers have conscientiously considered swimming performance to be scientific as explained in light of fluid dynamics. Generally, natural swimmers share two major propulsive strategies, including caudal-fin pitching propulsion (e.g. salmon, tuna, dolphins, and sharks) and travelling wave propulsion (e.g. eels and lampreys). When animals and humans swim, the motion of their limbs from the equilibrium to the extreme and from the extreme to the equilibrium may not be symmetric. We expect slower motion in the stroke from the equilibrium to the extreme (forward stroke) and a faster motion in the stroke from the extreme to the equilibrium (retract stroke). This novel waveform is examined in our recent work. We home in on the insight into the relationship between the kinematics and thrust or efficiency. This lecture will encompass (i) the hydrodynamic performance of a traveling wavy foil with varying foil kinematics (Strouhal number), fluid properties (Reynolds number), and foil deforming characteristics (wavelength), and (ii) enhancement of both thrust and efficiency using the hypothesized waveform.

Speech Title: Transitions in vibration mode and wake structure of a near-wall flexible cylinder at various yaw angles

Abstract:The multi-mode transition and vortex structures in the VIV of a near-wall flexible cylinder under different yaw angles are investigated through three-dimensional direct numerical simulation. Yaw angles α = 0°-60°, gap ratio G/D = 0.8, and Re = 500 are adopted. With the increase of α, the dominated vibration mode decreases from the 6th to 1st mode in the in-line (IL) direction and the 3rd to 2nd mode in the cross-flow (CF) direction. For the IL vibration, no mode transition occurs at α = 0°, whereas frequently mode transition is observed at α > 0°, due to the intermittent participation and spanwise competition of different modes, thus showing an intensified traveling-wave characteristic. For the CF vibration, mode transition is not excited at any α case even with spanwise mode competitions, due to the significant weight of the dominated mode, thus showing a strong standing-wave characteristic. The asymmetrical distributions of vibration displacements and force coefficients are established because of irregular energy transfer along the span. The spanwise vortex tubes at α = 0°-30° are separated into several cells associated with the dominated vibration mode, showing a locally parallel vortex shedding. However, positively-yawed and negatively-yawed vortex shedding are observed at α = 45° and 60°, respectively. The vortex strengths vary along the cylinder, where large-scale and small-scale vortices are observed at the CF anti-node and node planes, respectively. The Independence Principle (IP) is only valid at α < 15° for predicting the multi-mode vibrations and hydrodynamics, significantly reduced than that of α < 45° in the wall-free case or the mono-mode VIV case.

Speech Title: Scalable metamaterial thermally sprayed catalyst coatings for nuclear reactor high temperature solid oxide steam electrolysis

Abstract:The UK government in their 2021 Hydrogen Strategy recognises that the low carbon hydrogen plays a critical role in achieving transition to net zero and sets a target of 5GW of low carbon hydrogen production capacity by 2030 for use across the economy. Unfortunately, pure hydrogen cannot be found in nature and it has to be produced. Currently, the most common hydrogen production method is the steam methane reformation, where methane gas is reacted with steam to produce hydrogen. This process is very carbon incentive, but can be made low carbon with the carbon capture and storage, which does not exist yet. A better alternative is to use renewables electricity such as from solar, wind, nuclear to split water into hydrogen in an electrolyser achieving zero carbon hydrogen. Since there is virtually no zero-carbon hydrogen production plant in the UK, it will require a significant and rapid scale up of activities in research and commercialisation.
There are eight electrolysers at different stages of development and among those, solid oxide electrolyser technology has many attractive advantages to scale up to industrial scale. Its high temperature operation is suitable for utilising waste heat from industry. Moreover, excess stream generated in nuclear power plant can be easily utilised for producing hydrogen using solid oxide electrolyser. This talk will explore in detail the design of a solid oxide electrolyser including the use of different materials, how the design of each components affects the performance of an electrolyser and how optimising each component and operating parameters will improve performance. Finally, this talk will give a summary of our recently funded Energy and Physical Science Research Council (EPSRC) project on scalable metamaterial thermally sprayed catalyst coatings in improving solid oxide electrolyser performance. The talk will explain how metamaterial can be optimised through CFD modelling and experimentation, how it can improve flows inside an electrolyser and how it offers increased current density using similar size of an electrolyser.

Speech Title: Industrial decarbonization for sustainability

Abstract: One of the essential prerequisites for sustainable development and reducing the effects of climate change and global warming is decarbonizing the energy sector. The word “decarbonization” literally means the reduction of carbon dioxide emissions. Decarbonization is converting to an economic system to reduce and compensate for carbon dioxide (CO₂) emissions and other greenhouse gases. The long-term goal is to create a CO₂-free global economy. The industrial sector, in general, contributes significantly to the emission of atmospheric greenhouse gases. Industrial decarbonization represents the phasing out of carbon dioxide emissions from all aspects of industry without compromising competitiveness and prosperity. In this talk, different issues related to industrial decarbonization will be discussed, and some examples from developing countries will be presented.

Speech Title: Effective Teaching of Mechanical Engineering Design: Application of Lean Concept

Abstract: Mechanical engineering design has at least three features which distinguish it from many other teaching areas in the same discipline. Firstly, the majority of students have little or no background in engineering design, secondly, design learning is based on conceptual understanding (backward thinking), and thirdly lecturers are not much interested to teach mechanical engineering design due to complexity and no complete textbook. The main objective of teaching engineering design is to provide a clear understanding of machine design concepts with critical thinking. In addition, mechanical engineering design should train engineering students towards sustainability. As a result, the assessments of students’ performance become more difficult than teaching. The authors argued that application of lean manufacturing principle (The Toyota Way) can identify and then eliminate the wastes to make the teaching of mechanical engineering design appropriate and attractive to students and lecturers. The paper presents the findings based on students’ perception, feedback and assessment for 2015-2020 cohorts of students enrolled in a mechanical engineering design course at International Islamic University Malaysia. The main outcome of this research is to teach just sufficient and develop critical thinking.
