Computation of Flow Past a Hypersonic Cruiser,

Abstract

Numerical simulations of a hypersonic cruiser were accomplished by means of the mass-averaged Navier-Stokes equations at a nominal Mach number of six and a Reynolds number of fifteen million. The computations of flow at the zero and ten degree angles of attack were performed on a CRAY-1 computer utilizing a grid consisting of over 56,000 points. The present results adopting a branch-cut mesh system yielded superior numerical resolution over the previous solution using a wrap-around grid distribution. Numerical results are presented showing the detailed flow field structure, density and vorticity distribution, and velocity field. These results indicate that the wing-fuselage configurations investigated generates an unfavorable interference factor. (Author)
