Abstract

A numerical analysis is performed to investigate the effect of a supply channel and jet hole arrangement on the heat flow characteristics of impingement jet. The jet holes in a supply channel are composed of a single 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 single or staggered arrays is made.

유량공급 채널 및 제트 홀 배열이 충돌제트의 열유동 특성에 미치는 영향을 분석하기 위하여 수치해석을 수행하였다. 유량공급 채널 내에 있는 제트 홀은 전연면 채널의 중심축으로부터 일열 또는 엇갈림 배열로 되어 있다. ICEMCFD 소프트웨어를 사용하여 해석영역을 정렬 격자로 모델링하였으며, 수치해석은 CFD 코드인 CFX 15.0으로 수행하였다. 본 해석 결과의 타당성은 타 연구자들의 실험 및 수치해석 결과와의 비교를 통해 검증하였다. 일열 또는 엇갈림 배열인 경우에 충돌 제트의 질량유량 및 충돌면에서의 Nusselt 수 분포에 대해 비교 분석하였다.
