Numerical prediction of gas concentrations and fluctuations above a triangular hill within a turbulent boundary layer

On the improved finite volume procedure for simulation of turbulent flows over real complex terrains

“…It is based on the wind tunnel experiment by Costa et al presented in [54], in which the authors simulated atmospheric boundary layer conditions with a system of vortex generators, barriers and surface roughness. The same configuration was also used in a numerical study [55]. We use the mean velocity field at the domain inlet based on B flow type configuration defined in [54,55], which is characterized by the following power law profile…”

“…The grid size is N x × N y × N z = 160 × 30 × 80, which is the same grid resolution as in [55]. The RNG k − model [27] is used to calculate the turbulent viscosity.…”
