Two-component LDV investigation of three-dimensional shock/turbulent boundary-layer interactions
Mean velocity and turbulence measurements obtained by two-component laser Doppler velocimetry are presented, together with numerical predictions, for the shock-related separation of a turbulent boundary layer at Mach 2.85. The basic geometry--a 30 deg half-angle conical flare mounted on a long cylin...

| description | Mean velocity and turbulence measurements obtained by two-component laser Doppler velocimetry are presented, together with numerical predictions, for the shock-related separation of a turbulent boundary layer at Mach 2.85. The basic geometry--a 30 deg half-angle conical flare mounted on a long cylinder--is made three-dimensional by inclining the cone axis to the cylinder axis at an angle alpha . Cases studied include alpha of 0, 5, and 10 deg. The separation length and general upstream influence increase with alpha . A large-scale shock wave unsteadiness grows in amplitude with alpha and influences the amplification of turbulence correlations ahead of detachment. Scaling of the streamwise coordinate by separation length causes two- and three-dimensional data profiles on the cylinder to collapse for most measured quantities. The computed Navier-Stokes solutions show significant quantitative and qualitative departures from the data. |
