In the present study, we investigate the characteristics of thermal cavities in the rarefied flow regime using the Direct Simulation Monte Carlo (DSMC). We use a recently developed iterative technique to impose a desired wall heat flux boundary condition in the DSMC algorithm. Fluid mechanics and heat transfer behavior are studied over the walls and in the domain of the thermal cavity over a wide...
Micro/nano geometries with specified wall heat flux are widely encountered in electronic cooling and micro-/nano-fluidic sensors. In the present study we introduce a new iterative technique to impose a desired (positive/negative) wall heat flux boundary condition in the DSMC method that can be useful for simulation of Micro/Nano electro-mechanical systems (MEMS/NEMS) with given heat energy exchange...
