Kód oboru RIV: BK - Mechanika tekutin
A planar impinging air jet was experimentally investigated, with passive flow control as means of heat/mass transfer enhancement. An array of small cylinders was fixed at the nozzle lips so as to bridge the nozzle exit gap. Experiments used mainly the naphthalene sublimation technique (taking into account the heat/mass transfer analogy). Also measured were the local velocities. To quantify the heat/mass transfer effects, three procedures are proposed. Compared with the standard planar impinging jet at the optimal nozzle-to-wall distance, the enhancement of the average heat/mass transfer was demonstrated to reach up to 8%.
