- Abstract
- This paper introduces a pressure correction method for microflow computation.
Conventional CFD methods with no slip boundary condition fail to predict the
rarefaction effect of the wall when simulating gas microflows in the slip-flow
regime. Pressure correction method with an appropriate slip boundary condition
is an efficient tool in analyzing microscale flows. The present unstructured
SIMPLE algorithm adopts both the classical Maxwell boundary condition and
Langmuir boundary condition proposed by Myong. The simulation results of
microchannel flows show that the proposed method has an effective predictive
capability for microscale flows.
