摘要

摘要研究了降低大气中超音速飞行物体产生的冲击波强度的可能性。计算了薄体产生的近场和远场冲击波的参数，薄体前方有一个圆盘，圆盘穿过入射气流，入射气流的马赫数为 2。计算采用 "幻影体 "组合方法进行。计算结果表明，同时使用机体前方的空气动力表面和入射气流加热，可以将远场冲击波的强度降低约 30%。

Effect of Local Heat Supply into Supersonic Incoming Flow Ahead of Thin Body with Disk on Intensity of Weak Far-Field Shock Waves

Abstract

The possibility of reducing the intensity of shock waves from a body going supersonic in the atmosphere was investigated. Parameters of near- and far-field shock waves from a thin body with a disk located ahead of the body across the incoming flow at local heating of the incoming flow were calculated. The Mach number of the incoming cold air flow was 2. The calculations were performed by the combined “phantom body” method. The calculation results show that simultaneous use of an aerodynamic surface ahead of the body and heating of the incoming flow makes it possible to reduce the intensity of far-field shock waves by approximately 30%.

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
