A note on the replacement of 'universal profiles' in near wall zones using the finite element method
Abstract
The customary practice of using universal profiles to depict the variation in velocity and in the Van Driest equation to calculate turbulent viscosities in near wall zones is replaced by a simple finite element based model. In the near wall zone, finite elements are used to predict the variation in velocity and turbulence kinetic energy. The new technique is compared with the conventional 'universal profile' approach by solving a simple example.
