Impinging jet has large heat and mass transfer rates at and near the stagnation point. Especially, at a very low nozzle-plate spacing they have considerably large rates, but the flow resitance of nozzle-plate system becomes very large. In this study, the flow and heat transfer characteristics of self-resonating free or impinging jet having very low nozzle-plate spacing are dissussed experimentally, and it is made clear that the self-resonating free or impinging jet has a small flow resistance at a certain volume of resonating room and using the self-resonating impinging jet the heat transfer characteristics can be also improved.
