The objective of this thesis is to develop a new non-equilibrium wall model for large-eddy simulation (LES). The wall model is derived from the thin boundary layer equations (TBLE). A convective term model is proposed that reduces the TBLE to a set of ordinary differential equations. The new wall model is validated by a stand-alone simulation and by LES of turbulent channel flow and shock/turbulent boundary layer interaction. Coarse LES with the wall model compare well with LES with near-wall resolution. The results suggest that the error introduced by neglecting the convective term is much smaller than the error introduced by the eddy viscosity model. Thus, improvement of the eddy viscosity model is of paramount importance in wall modeling research.     «
