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...
In this study, we apply a hybrid direct simulation Monte Carlo (DSMC)/Navier–Stokes (NS) frame to simulate the effects of catalyst or splitter plates in propulsive efficiency of micro/nanopropulsion systems. Our hybrid frame uses the local Knudsen number based on the gradient of the flow properties (Kn GLL ) to distinct the continuum and molecular regions. This frame also uses the state-based...
