The calculation of incompressible three dimensional turbulent boundary layer
Abstract
A numerical calculation is made of the incompressible three-dimensional turbulent boundary layer induced by a circular cylinder erected on a flat plate. External pressure distributions are selected from flow theory and previous experimental data to investigate their effect on the development of boundary layers. Anisotropically distributed eddy viscosity is incorporated in a generalized mixing-length model of Reynolds shear stress. Good agreement was found between experimental and theoretical data which show that the effect of anisotropy in turbulence is not strong in the three-dimensional field. A discrepancy observed in the experimental data for the area near the separation line is considered to be related to the boundary layer assumption.
