Mean velocity and turbulence profiles, downstream of the jet orifice, in a 10 m/s crossflow have been measured over a range of Strouhal numbers and excitation powers for a jet/crossflow velocity ratio range of 1.3 to 4.6. This showed that acoustically exciting a jet flow causes significant increases in jet spread, penetration (up to 92% increase), and mixing. The jet mixing length was strongly reduced. Toroidal vortices were shown to be shedding from the jet orifice and produced profound… CONTINUE READING
