本文提出了燃烧的推进剂表面对外加谐声扰动响应的理论模型。对过去分析这一问题所做的很多假设均已放宽,包括粘性、表面任意波的入射和实际的二维平均流场的影响。为了确定声场-燃烧耦合的非线性特性,求解进行到波幅的二阶。采用一个接近实际的气相模型,可以合理地处理速度耦合和气流转向的影响。 In this paper, a theoretical model of the response of the combustion propellant surface to external harmonic disturbances is proposed. Many of the assumptions made in the past to analyze this problem have been relaxed, including the effects of viscous, incident surface arbitrary waves, and actual two-dimensional mean flow fields. To determine the non-linear nature of the sound field-combustion coupling, the solution proceeds to the second order of the amplitude. Using a near real gas phase model, the effects of velocity coupling and gas flow steering can be reasonably addressed.
