An Experimental Study on Flow Characteristics of Impinging Jet (1)

충돌제트의 유동특성에 관한 실험적 연구(1)

The flow characteristics of impinging jet flow are affected greatly by nozzle plate to distances. An sharp edge nozzle was used to achieve uniform mean velocity at the nozzle inlet, and its diameter is 10mm(d). Therefore, the flow characteristics on the impinging jet plate can be changed largely by the control of main flow. In the parent study, we investigate the effects of main flow length , its variable is nozle plate to distances( 12d, 10d, 8d, 6d and 4d).
