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

In the present work, we simulate rareed gas ow 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 eects of compressibility and rarefaction in the entire Knudsen regime and for a wide range of wall Mach numbers. Slip velocity, temperature jump, wall heat ux and wall shear stress are directly sampled from the particles striking the surfaces and reported for monatomic and diatomic cases for dierent rarefaction regimes. We also study deviation from the equilibrium using the probability density function for argon and nitrogen gas molecules.
