The disappointing numerical tests with a transitional low Reynolds number turbulence model
Abstract
A program package for the calculation of three dimensional incompressible turbulent boundary layer on three dimensional configurations, given only pointwise was developed. The package was based on an existing selfadaptive solution method for the three dimensional incompressible laminar boundary layer equations in streamline coordinates. The laminar equations were extended by a twoequation turbulence model (itself the extension of a two dimensional model). The low Reynolds number model should describe automatically also the transition to turbulence. This was a model with two equations for turbulence energy and lengthscale. Tests on an oblate spheroid show that the model, even when correctly scaled in two dimensions, fails completely in three dimensions.
