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 number.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 theequilibrium using the probability density function for argon and nitrogen gas molecules. https://scientiairanica.sharif.edu/article_3396_e7d6bcfbe40536abf2cb64c7258e36b0.pdf
