In this research, we provide the numerical model by using Lund's method for spatially-developing thermally stratified turbulent boundary layers. In order to generate the inflow turbulence, the turbulence parameters for velocities at recycle station are rescaled and introduced to the inlet boundary,while temperature is treated as a passive scalar. The generated inflow data for temperature as well as velocities are introduced into the main computational domain, where temperature is solved taking into consideration buoyancy effects. With this method, a long fetch is not necessary to simulate the spatially-developing boundary layer. We carry out LES analysis of the spatially-developing thermally stratified boundary layers. We investigate the turbulence structure inside turbulent boundary layers under both of unstable and stable conditions.
