Computational experiments on three-dimensional molecular diffusion in porous media

Alarcon V.J., Kingery W., Zhu J., Mississippi State University, US

Estimations of apparent diffusion coefficients usually consist of curve-fitting the output of one-dimensional models to experimental laboratory-measured data from porous aggregates shaped in different forms. In this research a computational exploration is presented on the [...]

Simulation of a Microfluidic Particle Concentrator and Separator

Chen C.C., Auner G.W., Industrial Technology Research Institute, TW & Wayne State University, US

A flow-through micro polymerase chain reaction (PCR) chip was optimized by using coupled multiphysics computational tools. Comprehensive simulations of temperature and flow profiles were presented for the denaturation, extension, and annealing zones on the flow-through [...]

Coupled Substrate-resonator-electrostatic Simulation and Validation fo High-Q MEMS Resonator Performance

Park K.C., Park Y.H., Park K.C., Park Y.H., University of Colorado at Boulder, US

Vibration energy transmission from MEMS resonator through anchor to substrate, viz., anchor loss, is examined by utilizing the coupled substrate-resonator-electrostatic numerical model. The resonator is electrostatically excited beam-type structure anchored at both ends onto multi-layered [...]
