| 摘 要： | 本文给出了V形壁面热膜测量物面摩擦应力的方法研究。实验表明该技术对三维湍流边界层中的摩阻测量是一类有效的方法。从本实验的数据可以看到,壁面热膜在二维湍流边界层中得到的校测函数能够直接用于三维湍流边界层的摩擦应力测量。

| Abstract: | A study of skin friction measuring technique by the v-shaped double surface hot film is presented. It can be found that this technique is a very promising device for measuring skin friction in 3D-turbulent boundary layers at least for attached region of 3D-turbulent boundary layers. And it seems true that the calibration functions of the surface hot film in 2D-flow can be directly used in the skin friction measurements of 3D-turbulent boundary layers. |
