Abstract

Numerical simulations of shock wave propagation in microchannels and microtubes have been performed using three different approaches: the Navier-Stokes equations with the velocity slip and temperature jump boundary conditions, the statistical Direct Simulation Monte Carlo (DSMC) method for the Boltzmann equation, and the model kinetic Bhatnagar-Gross-Krook (BGK) equation. The influence of the viscosity and heat-conductivity, the wall heat transfer losses, and the rarefaction effects has been studied and the results obtained with different approaches have been compared.
