Static and dynamic load balancing strategies were implemented for the direct simulation Monte Carlo (DSMC) method. Two problems, the ow around a capsule and steady shock wave reeection, were examined using the parallel DSMC algorithms. Up to 256 processors of an Intel Paragon were utilized in the computations.
This paper presents a series of tests that have been conducted to validate the collision models of the HawkDSMC implementation. These tests cover the hard sphere (HS), variable hard sphere (VHS), and variable soft sphere (VSS) collision models, and the Larsen-Borgnakke energy exchange model, for non-reacting gas mixtures. The results show that Hawkobtains… (More)
This paper presents computational results obtained with the direct simulation Monte Carlo (DSMC) method for several biconic test cases in which shock i n teractions and ow separation-reattachment are key features of the ow. Recent ground-based experiments have been performed for several biconic conngurations, and surface heating rate and pressure… (More)
