Development of an Analytical Wall-Function for LES

摘要

Although there have been several wall models proposed for the Large Eddy Simulation (LES), any of them has not been very successful in complex flows. Therefore, this study tried to develop an Analytical Wall-Function (AWF), which is effective to complex flows in Reynolds Averaged Navier-Stokes (RANS) simulation. The obtained results show that it is possible to apply the AWF to LES by defining the normalized viscous sublayer thickness dynamically.
