Abstract

The effects of favorable and adverse pressure gradients on the shape and pressure spectra of turbulent boundary layers are investigated. A contracting and then expanding wind tunnel test section is used for this investigation. Favorable (negative) pressure gradients are found to cause a modest reduction in the pressure spectrum levels compared to equilibrium flows. Adverse (positive) pressure gradients are found to dramatically increase the pressure spectrum levels and decrease the phase velocity.
