| Research Abstract |
A lattice Boltzmann method for micro/nanofluidics (μflow LBM) is developed. This μ flow LBM captures flow characteristic in the slip and transitional flow regimes at moderately high Knudsen numbers. Its results agree well with those of the DSMC and MD simulations. For complex micro/nano flow geometries, it is confirmed that the conventional second order discrete velocity models are good enough for simulating flow fields. Also, the presently developed macroscopic rough and permeable wall model is expanded to the LBM applications.
