In this study, we investigated the wall model for large eddy simulation by using flat plate boundary layer flow simulation. We conducted flow simulation by using different grid resolution, to find out the effect of grid resolution. We showed that the lack of resolution near the wall is affected to the overestimation of the production of kinetic energy. In addition to do simulation, we calculated the correlation between WRLES’s instantaneous flow and model’s result to evaluate the accuracy of the wall modeled LES by using spalding law as model. We found that there is no correlation between WRLES’s data and spalding law’s result.
