摘要
分析了跨流域流动特点、工程背景需求、国内外研究现状,针对高超声速飞行器跨流域气动力/热预测存在的主要问题,从粘性干扰参数与克努森数搭接的跨流域模拟准则、微量天平结构优化及测力技术、红外大面积中低量值热流测量技术、流场显示与测量技术和N-S/DSMC自适应紧耦合数值模拟方法等方面,总结了近年来取得的研究进展,并讨论了下一步研究方向。
The flow characteristics across different flow regions,engineering requires for aerodynamic force/heating predicting technique,and the research status in China and foreign countries are summarized.To solve the main problems of aerodynamic force/heating predicting techniques across different flow regions,some recent developments,such as the similarity criterion for experimental simulation based on viscous interaction and Knudsen number,framework optimization of microbalance as well as aerodynamic force measurement technique,the measurement of the middle and low heat transfer using infrared mapping,flow visualization and measurement,together with N-S/DSMC hybrid numerical method,have been presented,and further investigation is suggested.
