Abstract

In this study, a guide vane with varying positions and incidence angles was adopted to a pin-fin channel to analyze the change in thermal performance and pressure loss characteristics. A numerical analysis was conducted to investigate the effect of incidence angles and positions on heat transfer and flow characteristics at Re =1400. The results of it were compared those of a pin-fin channel without a guide vane. In case 1 when the incidence angle is $0^{\circ}$, the heat transfer performance is maximized and improved by approximately 5% when compared to the pin-fin channel without the guide vane. In case 2 when the incidence angle is $10^{\circ}$, the pressure loss is minimized and decreased by approximately 1.9% when compared to the pin-fin channel without the guide vane.

본 연구에서는 핀-휜이 있는 유로에 위치와 유동 입사각이 다른 가이드 베인을 부착하여 전열 성능 및 압력 강하 특성 변화를 분석하였다. 레이놀즈수가 1400일 때 가이드 베인의 위치와 입사각에 따른 전열 성능과 유동 특성을 수치해석으로 확인하였고, 핀-휜 만 있는 해석 결과와 비교하였다. 수치해석을 수행한 결과, Case 1의 입사각 $0^{\circ}$일 경우에 전열 성능이 최대가 되고 핀-휜 만 있는 유로에 비해 약 5% 향상되었다. Case 2의 입사각 $10^{\circ}$일 경우에 압력 손실이 최소가 되고 약 1.9% 감소하였다.
