Abstract

An experimental campaign was carried out to examine the effectiveness of film cooling on aerodynamic heating at hypersonic velocities. A flat-faced cylindrical model was tested at flow velocity of 2.5 km/s in a hypersonic shock tunnel. The test model was equipped with temperature sensors for convective heat flux measurement. The coolant gas, nitrogen, was injected through a 2 mm orifice housed at the center of the test model at different pressure ratios. Two different flow regimes were observed, steady and unsteady, with the steady flowfield having overall reduction in heat transfer compared to the unsteady one.

薄膜冷却对高超声速气流中空气动力加热效果的实验观察

为了研究薄膜冷却对高超音速气动加热的影响，我们开展了一项实验活动。在高超音速冲击隧道中，以 2.5 千米/秒的流速对一个平面圆柱模型进行了测试。测试模型配备了温度传感器，用于测量对流热通量。冷却气体氮气以不同的压力比通过一个位于试验模型中心的 2 毫米孔口注入。观察到两种不同的流动状态：稳定和非稳定，与非稳定流场相比，稳定流场的热传递总体上有所减少。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
