Ying, R., and V.M. Canuto, 1997: Numerical simulation of flow over two-dimensional hills using a second-order turbulence closure model. Bound.-Layer Meteorol., 85, 447-474, doi:10.1023/A:1000534921008.

We study turbulent flow over two-dimensional hills. The Reynolds streeses are represented by a second-order closure model, where advection, diffusion, production and dissipation processes are all accounted for. We solve a full set of primitive non-hydrostatic dynamic equations for mean flow quantities using a finite-difference numerical method. The model predictions for the mean velocity and Reynolds stresses are compared with the measured data from a wind-tunnel experiment that simulates the atmospheric boundary layer. The agreement is good. The performance of the second-order closure model is also compared with that of lower level turbulence models, including the eddy-viscosity model and algebraic Reynolds stress models. It is concluded that the present closure is a considerable improvement ove the other models in representing various physical effects in flow over hills. The feasibility of running a finite-difference numerical simulation incorporating a full second-order closure model on an IBM workstation is also demonstrated.
