Abstract
We use DSMC technique to investigate hydrodynamic and thermal characteristic of rarefied hydrogen flow in micro/nano lid-driven cavity. Flow behavior in all rarefaction regimes including slip, transition and free molecular ones has been studied. It is seen that center of primary vortex moves to the left and toward the drivenlid as Kn number increases. Moreover, wall shear stress and heat flux are decreased at higher degrees of rarefaction. It is also observed that wall slip motion is more pronounced in the slip regime and the slop smoothes as Kn grows.
