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

In the present work, we simulate rareed gas ow between two movingnano/micro parallel plates maintained at the same uniform temperature using the directsimulation monte carlo (dsmc) method. we perform simulations for monatomic argonand diatomic nitrogen gas and compare mon/diatomic gas behavior. for both gases, westudy heat transfer and shear stress and investigate the eects of compressibility andrarefaction 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 sampledfrom the particles striking the surfaces and reported for monatomic and diatomic casesfor dierent rarefaction regimes. we also study deviation from the equilibrium using theprobability density function for argon and nitrogen gas molecules.
