An Experimental Study of the Effect of a Compliant Surface on the Stability of a Blasius Laminar Boundary Layer and Its Transition to Turbulence and on the Coherent Structure

将进行9302381个施瓦茨实验，以表征边界层在涂有柔性、可抱怨的材料的平坦表面上的气流。系统地研究了表面柔度对边界层线性稳定性、向湍流的转变以及湍流减阻的影响。初步实验表明，在气流中有柔顺的表面是可以增加稳定性的。从柔顺表面减阻和湍流转变是已知的存在于液体流动中，具有重要的水力和液体泵送应用。对于空气或天然气，这项研究暗示了类似的节能可能性。***

9302381 Schwarz Experiments are to be conducted which characterize the boundary layer with air flow over a flat surface coated with a flexible, complaint material. The effect of surface compliance on linear stability of the boundary layer, transition to turbulence, and drag reduction for turbulent flow will be systematically explored. Preliminary experiments have been completed to demonstrate that increase of stability is possible with a compliant surface in air flow. Drag and turbulence transition reduction from a compliant surface is known to exist for flow of a liqud, with important hydronautic and liquid pumping application. For air or a gas, similar energy saving possibilities are implied by this research. ***
