Realistic boundary conditions for the simulation of atmospheric boundary layer flows using an improved k-ε model

Considering that, in general, the atmospheric boundary layer profiles might not satisfy the equations describing an unperturbed atmospheric boundary layer, turbulence models need to be corrected to guarantee the overall consistency of the approach. Former studies have addressed such a problem via the introduction of source terms in the transport equations of kinetic energy and turbulent dissipation rate, to guarantee consistency between the turbulence model and inlet profiles. In the present study, the formulation is further extended to improve the numerical stability of the approach as well as the realistic character of the produced profiles.
