【摘要】 本文提出了深度平均的k-ε紊流全场新模型,用来模拟热水或污染物注入大水体中的掺混、扩散和输移的全场流动及其混合规律。对陡河电厂大水域冷却池的实例进行了模拟计算,并与原体、模型观测资料进行了对比,得到较为一致的结果。更多还原

【Abstract】 A new depth-averaged k-e turbulence model for the entire water environment is proposed to simulate the flow and mixing in convective and diffusive transport of heated water and pollutants discharged into the large water body. Numerical modeling has been done for a cooling pool of large water body in Douhe Power Station. Comparisons of numerical predictions with in-site and model experiments show fairly good agreement.更多还原
