Paper Abstract

In the past 20 years, considerable progress has been made in the physical understanding and theoretical prediction of complex turbulent flow which can now be computed by solving the full time averaged Navier-Stokes equations. However, there is still a need to validate these calculations before their routine use in design procedure. The advent of LDV has allowed to obtain the detailed experimental information required to an in depth validation of Navier- Stokes calculations. The contribution of LDV to the development of advanced models is illustrated by presenting experiments performed in high speed flows. Two-dimensional transonic and supersonic shock wave/boundary layer interactions are first considered. Then axisymmetric base flows are examined. A three-dimensional configuration is discussed by considering a transonic channel. In each case, the LDV measurements are compared to computed results to illustrate the strong coupling that must exist between experimental and theoretical approaches.
