Abstract

An experimental/numerical study has been performed of sharp fin induced shock wave/turbulent boundary layer interactions at Mach 5. The experimental measurements included mean surface heat transfer and mean pressure distributions and surface flow visualization for fin angles of attack of 8- and 16-degrees. Additional data have been taken to study the conical nature of the surface properties. Time averaged conical Navier-Stokes calculations have been performed for these cases using the Baldwin-Lomax turbulence model. Careful examinations of the heat transfer distribution and of the performance of the numerical approach have been made. Although the surface pressure distributions can be collapsed using conical coordinates, the heat transfer distributions can not be collapsed. Instead, the heat transfer was found to be nearly constant along rays from a virtual conical origin determined from the pressure distributions. In appears that the conical Navier-Stokes approach does provide a reasonable engineering estimate of the interaction scales and local wall pressure and heating rates. However, room exists for improvement, especially in the area of turbulence modeling.
