Theoretical analysis and computer simulation of thick incompressible laminar/turbulent boundarylayer flows along curved surfaces
Abstract
Sets of boundary layer equations accounting for flow field nonuniformities such as curvature effects, normal stress and pressure variations as well as separation, are derived. The boundary layer flow domain is subdivided into a parabolic region where the fluid flow is approximately parallel to the submerged body, and an elliptic region which includes the line of separation where significant interactions between the boundary layer and the outer potential flow occur. Closure for the turbulent flow equations was obtained with submodels to the Reynolds stresses which reflect the effects of transverse curvature and longitudinal curvature as well as thickening of boundary layer. The accuracy of the parabolic equations was tested. For turbulent flow, the results of the derived set of parabolic boundary layer equations was compared with measured data sets for nonseparating flow over the tail of an axisymmetric body. The computer simulation model was written in FORTRAN IV, and documented in an easy to read user's manual.
