Abstract

To identify areas for improvement in RANS simulations for hypersonic flows, newly proposed compressible transformations are examined. The transformations are assessed to determine if they accurately collapse DNS data to the incompressible law of the wall and the effect of the transformation on the implied eddy viscosity is evaluated. Because the compressible transformation implies a specific form for the compressible eddy viscosity, an initial modification to the algebraic Baldwin-Lomax turbulence model is proposed as the first step of a new, compressible correction for RANS turbulence models.
