DSMC Simulations of Hypersonic Flows and Comparison With Experiments

This paper presents computational results obtained with the direct simulation Monte Carlo DSMC method for several biconic test cases in which shock interactions and ow separation reattachment are key features of the ow Recent ground based experiments have been performed for several biconic con gurations and surface heating rate and pressure measurements have been proposed for code validation studies The present focus is to expand on the current validating activities for a relatively new DSMC code called DS V that Bird second author has developed Comparisons with experiments and other computations help clarify the agreement currently being achieved between computations and experiments and to identify the range of measurement variability of the proposed validation data when benchmarked with respect to the current computations For the test cases with signi cant vibrational nonequilibrium the e ect of the vibrational energy surface accommodation on heating and other quantities is demonstrated
