Areas of Research
Dr Chin's key research areas concern the application of Computational Fluid Dynamics techniques and its experimental validation. Current work includes thixotropic flow of semi-solid alloys, transient and steady state flow in an electrically strictive driven poppet valve, entrainment process in supersonic flow ejector, mathematical and numerical modelling of industrial processes, semi-solid forming and metal casting. A new research area is the study of strongly coupled fluid-structure interaction applicable to physiological flows.
Dr Chin's research activities concentrate on the application of CFD techniques and experimental validation to engineering and physiological flow problems. One such example is that of thixotropic flow of semi-solid alloys into a die. Millions of automotive components are being produced annually by thixoforming (the shaping of metal components in the semi-solid state). The project aims to establish general rheological equations to characterise the flow behaviour of such alloys, which then can be included in a CFD program to predict the mode of die filling in thixoforming. Novel rheological experiments and numerical techniques for the solution of thixotropic flow are being developed.
Another aspect of Wen Chin's work is research into supersonic ejectors. Steam ejectors are cheaper to operate than a mechanical pump when a source of waste heat is available. Low grade waste heat has become increasingly available, e.g. from district heating plants or incinerators, and it is the opportune moment to re-introduce the use of supersonic steam ejectors in industrial refrigeration and air conditioning applications. A CFD program is used to investigate the mixing processes between supersonic and subsonic streams with the aim of improving the efficiency of the ejectors.
