Experiments have been carried out investigating13; the effectiveness of steady tangential blowing (inside the13; separation bubble) to control an axi symmetric separated13; flow at low speeds. Turbulent boundary separation was13; induced on a contoured afterbody and the separated shear13; layer reattached on a narrow cylindrical sting. Measurements made consisted of model surface pressures, mean velocity, turbulent shear stress and kinetic energy profiles using a 2-component LDV system. The results explicitly demonstrate that blowing downstream of the separation location, but within the bubble, can be an effective means of separation control, considering both wall and wake flow reversals.
