Claim One:
1. A method to compute turbulent flow, comprising of the following steps: reading object geometry for providing points on a surface of an object; establishing a computational mesh around said object; marking the computational cells in a region near the surface of said object; calculating turbulent flow field data in the entire computational mesh by solving the filtered Navier-Stokes equations using large-eddy simulation; substituting the sub-grid scale eddy-viscosity in said region near the surface of said object with a near-wall eddy-viscosity; said near-wall eddy-viscosity comprises of the sum of a Reynolds Averaged Navier-Stokes eddy-viscosity and the ratio of the product of the average of the resolved Reynolds shear stress tensor with the average strain rate tensor over the square of the average strain rate tensor multiplied by two.
