Experiments have been carried out investigating the effectiveness of steady
tangential blowing (inside the separation bubble) to control an axisymmetr
ic separated flow at low speeds. Turbulent boundary separation was induced
on a contoured afterbody and the separated shear layer reattached on a narr
ow cylindrical sting. Measurements made consisted of model surface pressure
s, mean velocity, turbulent shear stress and kinetic energy profiles using
a 2-component LDV system. The results explicitly demonstrate that blowing d
ownstream of the separation location, but within the bubble, can be an effe
ctive means of separation control, considering both wall and wake flow reve
rsals.
