Speech Title:Thin Film and Coating Development Using Physical Vapor Deposition Systems

Abstract: Several functional coatings (HAp, TiN, TiO2, Al2O3, CrAlN), were developed mainly for biomedical and automotive applications. The used of different Physical Vapor Deposition techniques like electron beam deposition, simultaneous vapour deposition and magnetron sputtering deposition, were utilized to deposit the coatings. The main objective of applying such coatings were to improve the overall mechanical performance of the parts or devices. Finite element method was carried out to ascertain the mechanical behaviour of the coating. Samples were subjected to relevant characterization analysis and physico-chemical tests. Tests were conducted to determine the mechanical properties of the coatings. Recently, a newly designed powder based magnetron sputtering system was successfully developed. A lot of exciting experiments were conducted using the system which is able to successfully sputter various type of ceramics, metallic and metallic alloy powders.

Speech Title: Prediction of Sand Erosion in a Crude Oil Choke Valve

Abstract: Two-phase turbulent flow of crude oil and sand in a plug and cage choke valve is analysed in the present article using 3D computational fluid dynamics simulations. The discrete phase model is used to simulate the sand particles flow and its interaction with the oil flow in the system. Parametric study is carried out to identify the governing parameters to minimize the sand erosion in the system. The valve geometry and dimensions are taken from an industrial oil production project. The parameter considered in the present study are the valve opening and the pressure difference in the inlet and outlet pipes. The simulation results are presented to show the erosion rate as a function of the valve opening and the pressure difference. It is found that the erosion rate is high for small valve opening as well as large valve opening. Minimum erosion rate is found when the valve opening is between 20-30% for all the cases with various pressure differences. Locations of maximum erosion rate are predicted in the simulations. The accuracy of the erosion rate prediction is directly affected by the accuracy of the available erosion correlation.

Speech Title: Preliminary Design for a Tidal Power Plant at Kuching Barrage

Abstract: Tidal energy is one of most predictable and reliable source of renewable energy. It is also considered as the most certain and conscientious source of renewable energy that is not yet fully established in East Malaysia. The main aim of the study is to determine the potential site for tidal range power throughout East Malaysia by studying the tidal range distributions. The tidal range data was obtained from Sarawak Marine Department and documented by using ArcGIS version 10.3 to show the position of the sites. The study also evaluated a potential tidal power generation site, and thereafter the estimated energy output from the chosen site. The power can be generated from structured barrage, and Kuching Barrage is the only structure available, located at Pending among all estimated sites. Kuching Barrage is an environmentally friendly site and there are no security issues and it did not obstruct the published shipping lane. The mean tidal range of Kuching Barrage is 4.2m and the maximum flow rate over one gate is 226.9m3/s. In order to determine a suitable system to harvest the potential tidal energy from the site, a turbine selection chart was used. The bulb-type turbine with a rated power of 5.2MW is identified as a suitable turbine to be deployed at the site. The estimation of annual energy output is calculated based on a theoretical method, with the average daily potential energy estimated to be 2.8MW, or approximately 5TWh per year.

Speech Title: New Lightweight Material for Automotive Application: Some Recent Developments and Potential Opportunities

Abstract: lightweight alloys are being increasingly used for applications, such as automotive and aerospace industries, where weight savings are critical. The strength of Magnesium alloy can be enhanced by adding proper amounts of certain alloying elements. In order to develop new alloy to achieve higher strength to compete with currently used metal alloys, it is important to understand the effects of alloying elements on the microstructure and mechanical properties. The addition of single Rare Earth (RE) to the alloy might result in great improvement in mechanical properties. Thus, the addition of proper amount of single RE into the alloy is one of the promising methods to improve the mechanical properties. Overall, the insights gained from this research will have a broad impact on understanding the strengthening behavior and microstructural evolution of RE-containing alloys, and such insights can serve as guidance for the development of new alloys and processes.
