충돌제트 노즐의 배열방법에 따른 열전달 특성에 관한 연구

In this paper. we present the flow and heat transfer charactetistics with the array of impinging jet nozzles by using the numerical computation and experiment. Numerical solutions were obtained for dimensionless gap H=6. dimensionless outlet length L=10 and Reynolds number He=1500 by using the commercial CFD code. CFX-5. Experimental and numerical results were agreed well with each other. It was found that the impinging jet with circular array nozzles generated the uniform heat transfer area and the maximum heat transfer is higher than rectangular array nozzles for certain parameter sets.
