A General Method for Calculating Three-Dimensional Incompressible Laminar and Turbulent Boundary Layers. II. Three-Dimensional Flows in Cartesian Coordinates


Book Description

The report presents a general method for computing three-dimensional laminar and boundary-layer flows in Cartesian coordinates. In the equations, the Reynolds shear stress terms are modeled by an eddy-viscosity formulation developed by the author. A very efficient two-point finite-difference method was used to solve the governing equations. The accuracy of the method is investigated for laminar and turbulent flows. (Author).













A General Method for Calculating Three-Dimensional Incompressible Laminar and Turbulent Boundary Layers. III. Three-Dimensional Flows in Curvilinear Orthogonal Coordinates


Book Description

This report summarizes the third phase of studies conducted on the computation of three-dimensional incompressible laminar and turbulent boundary layers. Solutions of the governing equations in curvilinear orthogonal coordinates are presented for a curved rectangular duct. In addition the small-cross-flow method developed by Cebeci, Kaups, and Mosinskis is applied to compute the boundary layer on a cargo ship hull. The method uses the eddy-viscosity concept to model the Reynolds shear-stress terms and uses a very efficient two-point finite-differnce method to solve the governing equations.

A General Method for Calculating Three-Dimensional Incompressible Laminar and Turbulent Boundary Layers. I. Swept Infinite Cylinders and Small Cross Flow


Book Description

The report presents a general method for solving the laminar and turbulent boundary layer equations for swept infinite cylinders and for small cross flows. In the equations the Reynolds shear stress terms are eliminated by using an eddy viscosity concept. An efficient two-point finite-difference method used earlier by Keller and Cebeci for two dimensional flows is used to solve the governing equations. The method has been programmed on the IBM 370/165. (Author).
