Comparison of Numerical Methods: DSMC Simulations and N-S Predictions on Bluff Bodies

  • Martin Gilmore
Conference paper


This paper compares predictions obtained using the Direct Simulation Monte Carlo (DSMC) technique to solve the Boltzmann equation and a Finite Volume technique to solve the Navier-Stokes equations for the flow around a bluff body in a hypersonic regime. Good agreement is obtained between the two approaches for computations of the flowfield around the Marsnet Semi-Hard Lander configuration travelling at Mach 30 at a simulated Earth altitude of 71 km. Predictions of density, temperature and heat transfer are presented.
