사각관로의 축대칭 공동부에서의 열전달
Heat Transfer in an Axisymmetric Cavity of a Rectangular Tube
초록
사각관로의 축대칭 공동부내의 흐름에 대하이 실험적으로 연구를 하였다. 공동부의 측벽과 대향벽에서 압력과 전달계수를 측정하였다. 공동부의 길이는 80mm에서
An experimental study for the flow in an axisymmetric cavity of rectangular tube was performed. The pressure and heat transfer coefficient along the side and opposite-walls of the cavity were measured. The cavity length was varied from 80mm to infinity during the experiment. As the result of this study, it was found that as the length of cavity increased beyond the reattachment point, the heat transfer coefficient decreased. It was also found that the mean heat transfer coefficient became maximum near the reattachment point.
