摘要：

The roughness parameters introduced in a refined k -epsilon turbulence model were optimized for relevant application on staggered arrayed cubic blocks. The roughness parameters were adjusted so that the values of calculated surface drag agree with those of experimental data. Variations of roughness parameters for the roughness volume density and the angle of roughness elements relative to the wind were obtained. Simulated flows using the optimized roughness parameters showed good agreement with experimental data.
