Abstract:

An open circuit oscillating flow wind tunnel was used to study the blowing requirements to maintain an attached turbulent boundary layer in an oscillating freestream flow with an adverse pressure gradient. Boundary layer separation was visualized through the use of tufts. Freestream flow oscillation frequency was found to have an effect on the blowing required to maintain attached flow. This frequency dependence exhibits characteristics which suggest resonant behavior.
