Numerical simulation of spatially-developing turbulent boundary layer with quasi-periodic boundary condition

摘要

Numerical simulation of spatially-developing boundary layer with quasi-periodic boundary condition is described. In order to reduce the CPU Cost associated with simulations of spatially developing problem, we used the method proposed by Lund. In this computation, the turbulent statistical data obtained from our simulations showed good agreement with profiles evaluated observations of atmosphere, which indicate validity of our simulations. The propriety of using quasi-periodic conditions for spatially developing problems was also discussed by investigating turbulent structures.
