Detailed investigation of hydrodynamics and thermal behavior of nano/micro shear driven flow using DSMC

In the present work, we simulate rarefied gas flow between two moving nano/micro parallel plates maintained at the same uniform temperature using the direct simulation Monte Carlo (DSMC) method. We perform simulations for monatomic argon and diatomic nitrogen gas and compare mon/diatomic gas behavior. For both gases, we study heat transfer and shear stress and investigate the effects of compressibility and rarefaction in the entire Knudsen regime and for a wide range of wall Mach numbers. Slip velocity, temperature jump, wall heat flux and wall shear stress are directly sampled from the particles striking the surfaces and reported for monatomic and diatomic cases for different rarefaction regimes. We also study deviation from the equilibrium using the probability density function for argon and nitrogen gas molecules. (C) 2013 Sharif University of Technology. All rights reserved.
