| description | The invention discloses a shock wave/boundary layer interference oscillation frequency prediction method based on the action quantity principle, and relates to the field of shock wave-boundary layer interference flow prediction.The method comprises the steps that S1, the relation between dissipation and separation length is given; and S2, giving a range of separation bubble oscillation, and obtaining a dimensionless frequency StL for predicting an oscillation frequency through an average period T of oscillation. The invention provides a shock wave/boundary layer interference oscillation frequency prediction method based on an action quantity principle. Through the method, the low-frequency oscillation frequency of shock wave/boundary layer interference flow can be effectively predicted.
本发明公开了一种基于作用量原理的激波/边界层干扰振荡频率预测方法，涉及激波-边界层干扰流动预测领域，包括：S1、给出耗散与分离长度关系；S2、给定分离泡振荡的范围，以通过振荡的平均周期T获得对振荡频率进行预测的无量纲频率StL。本发明提供一种基于作用量原理的激波/边界层干扰振荡频率预测方法，通过该方法将有效预测激波/边界层干扰流动的低频振荡频率。 |
