Computational study of the waverider aerothermodynamics by the UST3D computer code

Abstract

The paper describes the numerical simulation results for two models of the waverider. The aerodynamic characteristics as well as three-dimensional flow fields were calculated by the UST3D code. The splitting method is applied for the Navier-Stokes system integration. The solution is obtained by the time relaxation. The governing equations approximations are applied for unstructured tetrahedron grids. The UST3D code verification was performed by the first waverider model aerodynamics. The scramjet was integrated with the second waverider model. The engine energy deposition simulation was conducted by the source term addition into the energy equation. In this particular case aerothermodynamics parameters estimation is presented.
