摘要

为了对翼型动态实验中边界层转捩的测量问题及脉动压力信号处理方法进行研究,开展了翼型动态风洞实验,对不同振荡频率下的翼型表面边界层脉动压力特点及转捩判定方法进行分析。结果表明,基于脉动压力均方根值的转捩判定方法同样适用于翼型动态实验,动态实验下的脉动压力均方根值大于相同状态下的静态实验,且具有多个峰值,第一峰值位置具有很强的转捩特征,可以用其判定转捩。同时,动态转捩位置相对于静态有所提前。

Abstract

In order to study the measurement of boundary layer transition and the processing method of fluctuation pressure signal in airfoil dynamic experiment, an airfoil wind tunnel test is carried out to analyze the characteristics of boundary layer fluctuation pressure and the determination method of transition under different oscillation frequencies. Result shows that the transition determination method based on RMS in static experiment also applies to the dynamic, and the RMS value of dynamic experiment is greater than that of static experiment under the same state, and also has multiple peaks. The first peak position has a strong transition characteristic which can be used to determine transition position. Besides, the dynamic experiment has an earlier transition position than that of static.
