Abstract
In order to generate a rough-wall turbulent boundary layer, LES with pseudo-periodic boundary conditions and artificial fluctuation on inflow surface is carried out. Karman-type spectrum density function of atmospheric boundary layer with large turbulence scale can be simulated as same as the property of wind tunnel tests. As the result, the windward overturning moment in the along-wind direction can be simulated in lower frequency part.
