Abstract:
An investigation of five computer programs which calculate skin friction and boundary-layer integral properties in two-dimensional, turbulent, transonic flow was conducted. The five programs were of varying complexity and consisted of four boundary-layer-type methods with turbulence modeling varying from algebraic eddy viscosity models to a two-equation of turbulence model, and one mean flow compressible Navier-Stokes technique with algebraic turbulence modeling. The quality of the computed results was judged by comparison with available experimental data. For the data considered which were nonseparated, two-dimensional, transonic, adiabatic wall data, the most accurate calculations of skin friction were provided by an integral boundary-layer method and a finite difference boundary-layer method, both with algebraic turbulence modeling.
