| Abstract: | An experiment is made to prove a new universal method for the calculation of the steady in_ compressible plane Couette flow with a zero shear_stress plane.The experiment instruments are set on a experiment train of Beijing Subway. There are four set data are taken between the up_wall of the tunnel and top_wall outside of the train with constant train velocity. Two of which are full developed turbulent Couette flow, two of which are turbulent_laminar Couette flow. The measured velocity distribution with large range of Reynolds number and Couette shape factor are perfectly corresponding to the theory. A cheap and easy experiment method and also a simple and universal calculation method of plane Couette flow are proposed in this paper. |
