摘要

A wall-damping function is defined by the use of a Kolmogorov's velocity scale. A dissipation rate epsilon_SGS of SGS turbulent energy for components of a wave number smaller in scale than a grid filter size is not used as it is in place of a dissipation rate for components of all wave numbers of turbulent energy, but the dissipation rate epsilon_SGS of SGS turbulent energy for components of a wave number smaller in scale than a grid filter size is converted to a dissipation rate for components of all wave numbers of turbulent energy by a predetermined wave number (grid filter size) when turbulent flow is modeled and a distance from the surface of a wall.
