Annular Impinging Jet Controlled by Radial Synthetic Jets
Original language description
This experimental study focuses on generation and control of annular impinging jets. The annular nozzle was designed with an active flow control system using 12 synthetic jets. The experiments involved flow visualization and measurements of the wall pressure, time-mean flow velocity (by the Pitot probe), and wall mass transfer (by the naphthalene sublimation technique). Two main flow-field patterns (A and B) were identified. The patterns differ in the size of the separated-flow recirculation regions. The convective heat transfer was enhanced by 20 % at a moderate nozzle-to-wall distance, equal to 0.6 of the nozzle outer diameter.
