Accurate evaluation of damping in laterally oscillating microstructures is challenging due to the complex flow behavior. In addition, device fabrication techniques and surface properties will have an important effect on the flow characteristics. Although kinetic approaches such as the direct simulation Monte Carlo (DSMC) method and directly solving the Boltzmann equation can address these chall...

The transport of solutes and colloids in porous media is influenced by a variety of physical and chemical nonequilibrium processes. A combined physical-chemical nonequilibrium (PCNE) model was therefore used to describe general mass transport. The model partitions the pore space into "mobile" and "immobile" flow regions with first-order mass transfer between these two regions (i.e, "physical" n...

Deep neural network models have shown a great potential in accelerating the simulation of fluid dynamic systems. Once trained, these can make inference within seconds, thus be extremely efficient. However, they suffer from generalization problem when flow becomes chaotic and turbulent. One most important reasons is that, existing lack mechanism to handle unique characteristic turbulent flow: mu...
