强潮海湾温排水三维数值模拟

Numerical simulation of 3-D cooling water in the huge tidal bay

温排水排入海湾后,温差所产生的浮力效应,温排水趋于海水上层运移,随潮流的运动在呈现涨落分布。本文采用三维分层σ坐标斜压模型进行海湾流场和温排水温度场扩散的计算,通过分析温升场的平面温度和垂向温度分布,了解温排水对海湾温升的影响以及强潮海湾三维温排水的特点。

Due to buoyancy effect, the cooling water goes up to the surface of seawater after it is drained into the huge tidal bay. The cooling water presents itself the distribution of flood and ebb tide as the results of tidal flow moving. A integrated three-dimensional baroclinic flow model is used to simulate the tidal flow and temperature diffusion and dissipation. To analyze the temperature horizontal and vertical distribution, it is understood the cooling water effect on seawater temperature going up and three dimensional character of cooling water in the huge tidal bay.
