A SIMPLE INTEGRAL METHOD FOR THE CALCULATION OF THICK AXISYMMETRIC TURBULENT BOUNDARY LAYERS

In a recent paper the author examined the equations of a thick, incompressible, axisymmetric, turbulent boundary-layer and suggested, in a preliminary way, two different methods for their solution. In the paper, one of the methods, namely the integral approach, is considered in greater detail. It is shown that the development of the thick boundary layer can be predicted with acceptable accuracy by using an approximate form of the momentum-integral equation, an appropriate skin-friction relation, and an entrainment equation obtained for axisymmetric boundary layers. The method also requires the explicit use of a velocity-profile family in order to interrelate some of the integral parameters. Available experimental results have been used to demonstrate the general accuracy of the method. (Author)
