For large-scale structures in the atmospheric boundary layer (ABL), the Coriolis effect and near-wall behavior can have a meaningful impact. For example, both the Coriolis effect and blade boundary layer impact how muchpower wind farms produce. RANS simulations of the ABL typically use the ..kappa..-epsilon turbulence model, which has been developed to accurately capture the Coriolis effect but typically does not perform well near walls. The SST turbulence model performs well near walls but does not accurately capture the Coriolis effect. This work modifies SST to accurately model the Coriolis effect. We discuss the similarities and differences in how to modify ..kappa..-epsilon and SST for the Coriolis effect. Finally, we compare ..kappa..-epsilon and SST simulations of the ABL, including the Coriolis effect, with large eddy simulations and measurements.
