| 内容記述 | A large number of velocity profile families have been proposed for various types of flows relative to the integral method solution of boundary layer equations. An extensive survey revealed that of them were universally applicable in the sense that for the laminar layer, for example, could not be applied to transition or turbulent layers, and vice versa. The purpose of this paper is to propose a new unfied velocity profile family which is valid to laminar, transition and turbulent boundary layers as well as turbulent wake. The profile family is based on a quasi-universal velocity defect law, the similarity law for mean velocity fields observed from a frame of reference moving with the speed of UM(the mean velocity at y=0.45δ). The profile family nominally prossesses six characteristic parameters. However, good empirical correlations exist for some of them, which can reduce the number of parameters. Particular usefulness for integral calculation methods is expected. A similarity law for turbulent shear stress distributon in fully developed turbulent shear layers is also proposed. | |||||||||
