A numerical simulation is performed to study the characteristics of the gas cross flow over an array of rectangular cylinders in a two dimensional microchannel. Since Direct Simulation Monte Carlo (DSMC) suffers from the statistical noise for low Re flows which are often encountered in micro-flows, the non-isothermal Information Preservation (IP) method is employed. Pressure boundary conditions based on the characteristic theory are implemented at the inlet and outlet domain boundaries. The simulation results are presented. This study will form a base for our future particle-atomistic hybrid computations.
