Abstract
The paper solves the spectral equation of turbulent kinetic energy for a steady-state and stable horizontally homogeneous flow. Differently from latter approach it explicitly considers a model for the divergence of spectral energy due to pressure fluctuations. Using Green’s function it is postulated that this divergence is a linear combination of the other terms of the spectral equation. Physically acceptable results indicate that it can be dependent only on the second and third derivatives of the spectrum function. The model’s results show good agreement with previous studies as well as clear dependence with stability parameters according to the observations done by Kaimal et al.
