Abstract
Accurate and high speed estimation method of pressure flow factors for ultra thin spacings with surface roughnesses using DSMC (Direct Simulation Monte Carlo) technique is proposed as hydrodynamic air bearing problems. The 2-dimensional pressure flow factors for parallel flat plates calculated by the method give good agreement with the value obtained by the linearized Boltzmann equation based on hard sphere model and BGK model.
