Abstract:

The pressure gradient effect on the characteristics of a compressible turbulent boundary layer in separation and reattachment regions of laminar and turbulent flows have been investigated. Experiments were conducted at a large variation of Mach numbers and free stream Reynolds numbers. Favorable pressure gradient was found to have significant effect on the correlation of the total temperature and velocity profiles in turbulent boundary layer. Correlations for the separation distance, peak heating values, and peak surface pressure were found. Methods are described to predict the location and peak heating values in a separated flow region.
