The flow Analysis in a Microchannel using the Lattice Boltzmann Method

격자볼츠만방법(LBM)을 이용한 마이크로채널 내의 유동해석

As an alternative numerical method, the lattice Boltzmann method (LBM) is used to simulate a 2-dimensional pressure driven microchannel flow which comes from frequently in MEMS problems. The flow is assumed to be isothermal ideal gas flow. The flow field is calculated with various Knudsen numbers, pressure ratios and aspect ratios of the microchannel. The LBM can show the fundamental characteristics in microchannel flow such as velocity slip and nonlinear pressure drop.
