Numerical simulation of supersonic flows over ballistic models using UST3D programming code

Abstract

Computer modeling of a flow over two hypersonic ballistic configurations using UST3D programming code elaborated in Laboratory of Radiative Gas Dynamics of Ishlinsky Institute for Problems in Mechanics was carried out. The first configuration represented blunted cylinderflare geometry, while the second was standard HB-2 ballistic model. Simulation results showed good accordance with various experimental and numerical tests data. Non-viscous versions of UST3D code were developed to testify the numerical method validity on tetrahedral meshes. Numerical cases with the same two geometries were examined to determine solution discrepancy between non-viscous and original algorithmes. Agreement of numerical results obtained with non-viscous solver using slip boundary conditions and the original code was observed. This research demonstrated UST3D method validity for the considered range of problems.
