충돌제트에서의 유량공급 채널 및 제트 홀 배열에 따른 열전달 특성 수치해석

A numerical analysis is performed to investigate the effect of a supply channel and jet hole arrangement on the heat transfer of impingement jet. The jet holes in a supply channel are composed of an in-line or staggered array from the center of a leading edge channel. The software ICEMCFD is used to generate the structured grids for calculation domain and a CFD code CFX 15.0 to perform the simulation. The present solutions are validated by comparison with the experimental and numerical ones of others. A comparison of mass flow rates of impingement jets and Nusselt numbers on the impingement surface for the in-line or staggered arrays is made.
