   Sammanfattning : This thesis presents two new numerical wall models for computing Reynolds-Averaged-Navier-Stokes (RANS) equations with low-Reynolds-number turbulence models. Theobjective is to considerably reduce the total central processing unit (CPU) cost of thenumerical simulations of wall bounded flows while maintaining the accuracy of anylow-Reynolds-number turbulence model.
