摘要
在翼型模型的表面粘贴表面热膜,由其给出脉动电压的均方根值和波形图,可测出层流边界层分离点和湍流边界层再附点,转捩分离泡的位置也就确定了。
An experimental study was undertaken to locate the transitional separation bubble which often occurs on airfoil operating at low Reynolds numbers. The surface.hot film gages on the surf ace of airfoil gave the oscillograms of a voltage and the RMS value of a fluctuating voltage. The points of laminar boundary layer separation and turbulent boundary layer reattachment were obtained from these results. Then the transitional separation bubble was located.
