摘要: In the present study, we investigate characteristics of micro/nano thermal cavity in rarefied flow regime using direct simulation Monte Carlo (DSMC) method. We use a recently developed iterative technique to impose desired wall heat flux boundary condition DSMC solver. Hydrothermal and transfer behaviors are studied over walls inside domain wide range Knudsen number slip transition regimes. Finally, consider effects molecular structural parameters on hydrodynamics flows.
