有压环隙科特（Couette）流的实验研究

The Experimental Research on Couette Flow With Pressure Between Concentric Cylinders

本文公布了有压环隙科特流的21组实验曲线,这些曲线是在剪切流已充分发展而泰勒涡尚未生成的条件下测得的。由于采用了二维多普勒激光测速仪以及新发展的三光束光路,取得了十分贴近动壁、并覆盖整个测量截面的较完整的二维速度的信息。这些资料的公布,无疑对发展有压环隙科特流的实验与理论研究工作将起到重要的作用。

Twenty-one groups of experimental curves of Couette FloW with pressuee between concentric cylinders are disclosed in the paper. Those curves are measured under the conditions of the fully developed Shearing flow and the Taylor Vortex are not yet formed, by the adoption of 2-D LDV and the newly developed three beams system, the perfect velocity survey to the approachlng moving surface and the full range of a two dimension measurement of the imcompressible flow are obtained no doubt, the disclosure of these information will play an important role both on the development of the theoretical research and experiment of Couette flow with pressure.
