近岸海域电厂温排水数值模拟

Numerical Simulation of Thermal Discharge in Coastal Area

建立了守恒性好且能贴体模拟工程区域的二维水流-温水扩散数学模型,采用三角形网格划分计算区域,有限体积法求解水深积分方程。通过实测潮位潮流资料验证了模型的合理性,并在此基础上对近岸海域某电厂温排水的空间分布进行了预测计算,其结果为电厂设计和环境评价提供了依据。

A 2-D numerical model with fine conservation was established for simulating the current and temperature field, body-fitted triangle mesh was used to discrete computation area and finite volume method was applied to solve the water depth-integral equations. The simulated results agreed well with the measured data, so the rationality of the model was certified. The current and temperature fields were simulated to forecast the temperature distribution around the plant, and the results provided references for power station design and environmental assessment.
