Research Abstract	We have devised a new simple kinetic-equation model which can simulate supersonic flows and aerodynamic sound. This model is based on the free-molecular-type kinetic equation whose calculation system was constructed by Sone in 2002. Various numerical simulations are carried out to confirm that this model can compute supersonic flows and show that numerical results agree with the corresponding solutions of the compressible Navier-Stokes and Euler equations.
