【摘要】 <正> 多年来,应用传统的稳态实验方法,对如图1所示的流场的研究已取得一些成果,但还需要发展新的测试方法和手段进行深入研究。本文应用瞬态方法,在卢德维格风洞里对该流场进行传热实验研究,得到一些新的结果。更多还原

【Abstract】 Measurements for air flow downstream of a backward-facing step with a constant wall temperature by transient technique are presented in this paper. The results are compared with available computation data and experimental data by traditional technique. It demonstrates that the transient technique is a new effective method of heat transfer research in separated flow field.更多还原
