Prof. Dr. Nawaf Hazim Saeid, Universiti Teknologi Brunei, Brunei

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: Themo-mechanical Interfacial Stress Analysis in Electronic Packaging at Different Temperature Conditions: A Review from Author's Work

Abstract: The study of thermal mismatch induced stresses and their role in mechanical failure is one relevant topic to composite materials, photonic devices and electronic packages. Therefore, an understanding of the nature of the interfacial stresses under different temperature conditions is necessary in order to minimize or eliminate the risk of mechanical failure. An accurate estimate of thermal stresses in the interfaces plays a significant role in the design and reliability studies of microelectronic devices. In the microelectronic industry, from a practical point of view, there is a need for simple and powerful analytical models to determine interfacial stresses in layered structures. This review paper summarizes the work conducted by the authors in relation to the bi-layered assembly with different temperature conditions on the determination of interfacial thermal stresses. The authors have extended the case of uniform temperature model by earlier researchers of two layered structure to account for differential uniform temperatures, linear temperature gradient in the layers. The presence of a heat source in one layer (die) is also presented. Finally, the effect of bond material properties and geometry on interfacial stresses and bond material selection approach are also considered in a simple way.

Prof. Rosli Bin Ahmad, Universiti Tun Hussein Onn Malaysia, Malaysia

Speech Title: New Lightweight Materials for Automotive and Aerospace applications: 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 Aluminium (Al) and Magnesium (Mg) alloys can be enhanced by adding proper amounts of certain alloying elements. In order to develop new alloys 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.
