摘　　要：以罗源湾内可门电厂取排水工程为例,利用ECOMSED海洋水动力模型,对其水域潮流场和温度场进行了三维数值模拟,模型计算得到的潮位、潮流和温升范围均与电厂运行期间的原体观测资料吻合良好。在此基础上,对电厂已建工程不利工况下温排水的水力热力特性进行了模拟计算,获得了其温升影响范围、垂向温升分布及取水温升。计算结果表明,ECOMSED模型可应用于电厂近区温升预测,能体现冷热水的分层现象。Taking the Kemen power plant in Luoyuanwan as an example, the marine hydrodynamic model ECOMSED was used to simulate three-dimensional tidal field and temperature field. The tidal level, tidal current and temperature r{se range obtained by the model were consistent with the original observation data. On this basis, the hydraulic and thermo- dynamic properties of the cooling water were simulated under the most unfavorable conditions of the built project of the power plant. And the influence area of temperature rise, vertical distribution of temperature rise and temperature rise of getting water were obtained. The result shows that the ECOMSED model can be used to predict the temperature rise near the power plant and the temperature stratification phenomenon can he reflected.
