Direct/inverse, compressible turbulent boundary-layer computations using a two-equation turbulence model
Abstract
A compressible, turbulent, boundary-layer prediction code has been developed which can be used in the direct and inverse modes to compute two-dimensional and axisymmetric, attached or separated, boundary-layer flows exhibiting a large variety of streamwise pressure distributions in transonic and supersonic regimes. Turbulence is modeled by the high Reynolds number form of the (k-epsilon) model. Wall function formulas are employed in the near-wall region. The boundary-layer equations are solved using the Keller box scheme. The Reyhner-Fluegge-Lotz approximation is employed in the reverse-flow region. A number of test cases are computed and comparisons are made with experimental data.
