A 3-Dimensional Numerical Simulation Model of Recirculation and Turbulence in Open-Air Mine with Fine-Mesh, Nonhydrostatic
深凹露天矿内复环流和高湍能区的三维细网格非静力模拟

A three-dimensional nonhydrostatic atmospheric boundary-layer numerical model was used to study the characteristics of flow and turbulence in a small-scale deep open-air mine Considering small scale and complex terrain, in this model we use simple energy closure scheme without hydrostatic approximation A real case of an open-air mine, was simulated Results indicated that the ratio of mine depth to width and the inflow shear obviously affect the flow and turbulence in the pit Some results obtained from this model were in agreement with the wind tunnel experiment under the same conditions
