内容記述 | A simple and practical method is presented to calculate the turbulent boundary layer on a rotating cone with the radius decreasing toward downstream. Fundamental assumptions are the generalized quasi-collaterality and a skin friction law of power law type. Predicted results of the method agree excellently with the experimental value of momentum thicknesses. Measurements of Reynolds stress have been performed by use of two types of rotated hot wires. The three components of turbulent intensities show very large growth with the rotating speed of the cone. Also the Reynolds shear stress components exhibit big effect of the speed ratio. Turbulent energy production and transport terms computed from measured quantities show the importance of the novel terms. | |||||
