dc.description.abstractThis experimental study focuses on generation and control of annular impinging jets. An annular nozzle was designed with an active flow control system using twelve radial synthetic jets issuing from the central body of the nozzle. Measurements of the wall pressure and wall mass transfer were performed with air as the working fluid. The control action causes modification of the flowfield resulting in changes of the corresponding heat/mass transfer distributions. The convective transfer rate on the stagnation circle can be demonstrably enhanced by 20% at a moderate nozzle-to-wall distance, equal to 0.6 of the nozzle outer diameter.en_ZA
