摘要：
This paper presents some of the results of numerical simulations of flow in the proximity of significant artificial terrain obstacles. The mathematical model is based on Reynolds averaged Navier-Stokes equations for incompressible flows. Turbulent closure of the model is obtained by a simple algebraic turbulence model. The numerical solution is carried out by the semi-implicit finite-difference scheme. The results of simple tests are presented and summarized. Model sensitivity has been studied with respect to the simulated obstacle size and shape.
