The application of the single-sianted hot-wire technique in the three-dimensional flow field
单一倾斜热线探头在三维湍流场中的应用

This paper describes fundamentals analysis way of the single-slanted multi-position hot-wire technique and its application to the three-dimensional flow field, such as turbulent boundary layer through gaps between roughness elements. Comparisons are made for the mean velocity, turbulent intensity, and Reynolds shear stresses profiles. The measurement result to turbulent wall boundary shows that more correct experiment result will be gotten when higher degree correlation items for mean velocity and turbulent intensity are taken into consideration.
