Ying, R., V.M. Canuto, and R.M Ypma, 1994: Numerical simulation of flow data over two-dimensional hills. Bound.-Layer Meteorol., 70, 401-427, doi:10.1007/BF00713778.

We have studied a neutrally-stratified flow over two-dimensional hills using a two-dimensional, non-hydrostatic version of the Regional Atmospheric Modeling System (RAMS). We have implemented three different turbulence closure models: the standard E-ε mode, an Algebraic Reynolds Stress Model (ARSM) and a new E-ε-ave(u*w) model. Model predictions for the mean and turbulence closure flows using different closure schemes are compared with the data of a wind tunnel experiment containing isolated two-dimensional hills of varying slope. From the comparison, it is concluded that all three models predict the mean flow velocities equally well while only the new E-ε-ave(u*w) closure model accurately predicts the turbulence data statistics.
