摘要
二维粗糙带是常用的加速流场转捩的流动控制方式,理论分析并用风洞实验研究二维粗糙带作用下的高超声速平板边界层引起的波前畸变特性。采用波前检测系统测量高超声速边界层流场的波前畸变,对比有无粗糙带情况下的流场波前分布。研究结果表明,在高超声速平板边界层发生转捩以前,高精度波前测量系统不仅可以给出高速流场的波前分布,同时还可以计算对应的密度场。实验结果还表明,马赫数为5的边界层流场明显失稳时波前畸变有大幅度提高;同时通过对比有无粗糙带时波前畸变特点发现,平板壁面加粗糙带后尽管边界层的流态未发生变化,但相同位置的平均波前、波前均方根和峰谷值明显增大。
Abstract
Two-dimensional strip is a common flow control method to accelerate flow transition. The wavefront distortion resulting from hypersonic boundary layer has been investigated in virtue of theoretical analysis and wind tunnel experiments. Wavefront measurement system is used to measure the wavefront distortion of hyper-sonic boundary flow, and compare the distribution of flow wavefront with and without strip. The results prove that high-precision wavefront measurement system can present not only wavefront but also density distribution be-fore the flow transition of boundary layer. In addition, the experimental results show that the wavefront distortion increases quickly when the flow is obviously unstable. Finally, comparing the distribution of wavefront induced by strip with the corresponding data without strip, we find that the mean wavefront, root mean square and peak-valley value of wavefront with strip are much larger than that without strip.
