本文研究了收敛通道内一侧壁上分别具有孤立气膜孔、多排气膜孔以及气膜孔与矩形肋复合的传热特性。用热敏液晶作为高分辨率的表面温度指示计,提出了详尽的强化传热因子的图谱,用表面切应力敏感液晶显示了该传热面上的流动图型。
In this paper, the heat transfer characteristics of isolated gas film holes, multiple gas film holes and gas film holes and rectangular ribs on one sidewall of the convergent channel are studied respectively. Using the thermosensitive liquid crystal as a high-resolution surface temperature indicator, a detailed map of the enhanced heat transfer factor is presented, and the flow pattern on the heat transfer surface is shown by a surface-shear-stress sensitive liquid crystal.
