Abstract

Gas molecular motion around laser opto-microengines are numerically simulated by the Direct Simulation Monte Carlo method. The flow model for simulation is that four blades rotor of the engines is installed, without rotation, in a computational domain. The domain, a square cavity, is enclosed by solid surfaces with diffused reflection. The backward surface temperature of the rotor is lower than the forward surface temperature by 2 times. It is revealed that the maximum macroscopic velocity around the rotor is dependent on the blade thickness.
