An Implicit Numerical Solution of the Turbulent Three-Dimensional Incompressible Boundary Layer Equations.

摘要: A method of solving the three-dimensional, incompressible turbulent boundary-layer equations was developed using a Crank-Nicholson implicit finite-difference technique, with stress terms modeled an eddy-viscosity model obtained from mixing length theory. The applied to two three-dimensional flow geometries for which experimental data exists and comparison this showed excellent agreement. complete computer program sufficiently generalized application two-dimensional laminar flows arbitrary pressure gradients. several such test cases solutions agreed well both theory experiment. An analysis presented determine conditions finite difference were stable convergent. (Author)
