Heat Transfer Cost-Effectiveness of Nanofluids

Xu D., Pan L., Yao Q., Institute og High Performance Computing, SG

When metal or oxide nano particles are dispersed in fluids to form nanofluids, the particles will improve the thermal conductivity of the fluids. Therefore, it is suggested to use nanofluids as coolant to improve heat-exchanger [...]

Full Coupling Simulation of a Membrane Micropump

Yao Q., Xu D., Pan L.S., Melissa Teo A.L., Ho W.M., Peter Lee V.S., Shabbir M., Institute of High Performance Computing, SG

The design of PZT actuated valveless membrane micropumps is a very complex process as it involves the knowledge of electro mechanics, solid mechanics and fluid mechanics. So far, there is no accurate, flexible and broadly [...]

Application of Local Radial Basis Function-based Differential Quadrature Method in Micro Flows

Xu D., Ding H., Shu C., Agency for Science Technology and Research, SG

Numerical simulation of flows in micro geometry is one of the most appealing fields in computational fluid dynamics due to the advent of MEMS. In the present study, a local Radial Basis Function-based Differential Quadrature [...]

Development of Patterned SMA Strips as Self-Heating Resistors

Chen J., Cheng X.L., Cai B.C., Xu D., Wang L., Cheng X.L., Shanghai Jiao Tong University, SG

A way to develop the pattern of shape memory alloys (SMA) titanium-nickel (TiNi) strips for improving the actuation performance of membrane microactuator is described in this paper. The patterned SMA strips serve not only as [...]
