Abstract– Current vehicles travel at supersonic and hypersonic speeds, with next-generation vehicles traveling at even faster speeds. To fully study physics at hypersonic speeds, a numerical study is conducted to observe the effects of supersonic and hypersonic flow over certain objects. Three sets of simulations are created, with each simulation building from the previous one, to study high-speed airflow on vehicles. Simulations are designed based on compressible Euler equations (mass, momentum, and energy) [10] and well-studied fluid physics models to observe the shocks, air particle dissociation, and physics of the flows. Data from each run is collected and compared with corresponding theories to verify the accuracy of the simulations and theories. Results from each study, especially the last set of simulations, have applications to commercial and defense fields, such as for projectiles, aircraft, and spacecraft.
