LES of spatially-developing stably stratified turbulent boundary layers
Details
The turbulence structure and the transport process of various types of material in thermally stratified turbulent boundary layers have not been sufficiently understood yet, because the flow characteristics are sensitively deformed by the buoyancy effect and become very complicated. In this research, we carry out LES analysis of the spatially-developing stably stratified turbulent boundary layers and investigate the streamwise variation of turbulence structures. Also, through the comparison with the turbulent channel flows which was simulated using the LES technique by Armairo and Sarker(2002), interesting features of a spatially developing stable boundary layer are clarified.
