The structure of turbulent boundary layer with adverse pressure gradient corresponding to turbomachinery condition

Materny M, Dróżdż A, Drobniak S, Elsner W

The paper deals with the experimental analysis of turbulent boundary layer at the flat plate for large value of Reynolds number equal Reθ ≈ 3000. The adverse pressure gradient generated by curvature of the upper wall corresponded to the case of pressure variation in axial compressor. The fully developed turbulence structure was achieved by proper triggering of the boundary layer. The mean and turbulent flow – fields were investigated with the use of hot–wire technique.

The paper deals with the experimental analysis of turbulent boundary layer at the flat plate for large value of Reynolds number equal Re??3000. The adverse pressure gradient is generated by curvature of the upper wall and corresponds to the case of pressure variation in axial compressor. The analysis is concentrated on the problem of scaling of turbulent boundary layer and on the physical background behind scaling laws being compared. The results obtained suggest, that boundary layer at APG conditions requires two velocity scales, i.e. inner (imposed by inner boundary condition) and outer (imposed by outer layer) velocity scales.
