摘要
提出了深度平均的应力—通量代数全场模型，用来模拟热水侧向排入大水体的各向异性的输移扩散规律。应用有限体积法对控制方程进行离散，利用ＳＩＭＰＬＥ法进行数值模拟。通过该模式的模拟计算给出了速度场、温度场的分布。所得的回流区形状及温度场分布与深度平均的ｋ－ε模型及实验资料对比。
The depthaveraged stressflux algebraic (DSFA) model is developed to
simulate the aniostropic transport and dispersion when the hot water or pollutants are side
discharged into the large body waters. In this model the equations are discreted by the Finite
Volume Method (FVM) and solved by SIMPLE procedure. The results of the numerical simulation
give the velocity field and temperature field. The predicted size of the recirculation zone and
isotherms are compared with the experiment and results of k- model and the DSFA shows better
agreement with the experiment.
