ABSTRACT

As the development of microelectromechanical systems (MEMS), the flow in microdevices has become an area that receives a significant attention. This paper is concerned with application of the entropic lattice Boltzmann method (ELBM) to simulation of two-dimensional flows in microgeometries. The use of the ELBM for microflow simulation is a good idea because it is based on the Boltzmann equation which is valid for the whole range of Knudsen numbers. In this work the ELBM is applied to simulate gaseous flows in a microcavity and a microchannel for different Knudsen numbers. The obtained numerical results show that the ELBM can be used properly for simulating microflows in slip regimes.
