A mixture of different small particles in a base fluid has been used as a method to enhance the rate of heat transfer for various heat transfer instruments . One of the reasons is that the thermal conductivity of metal and carbon nanostructures exhibiting much higher thermal conductivity than base fluids . Present research investigates the impact of functionalized colloidal suspension on heat transfer . Our aims are to develop heat transfer media and modify conduit geometry to improve the turbulent convective heat transfer performance .
Moreover , we conduct investigation on heat transfer and pressure drop characteristics in various heat exchanger geometries to obtain enhanced heat dissipation . Both the experimental and numerical studies will be performed to evaluate the characteristics of different colloidal suspensions . The current research will reduce carbon footprint , create economic benefit and protect the environment . We also work closely with the University of Malaya and the National Energy University .

Soft Functional Materials : Theory , Simulations , & Experiments

Dr Goh , Kek Boon Lecturer PhD
Research expertise : Coupled Problems , Modelling & Simulation , Transport Phenomena , Soft Materials , Mechanics
We are interested in understanding how soft materials behave when pushed to their limits . Our group covers all aspects of bulk and interface mechanics , such as instabilities / growth / damage / fracture / deactivation , and its associated transport phenomena at different length and time scales . The mass , heat , and momentum transport mechanisms leading to materials ' functional properties are also of interest . In brief , we couple theoretical , simulation , and experimental approaches to examine the mechanics and transport phenomena in soft materials .
