滨海火、核电厂温排放数值模拟研究进展

Advances in numerical simulation of thermal discharge of heat or nuclear power plants in coastal areas

回顾近年来国内外滨海火、核电厂温排放数值模拟研究的进展,着重讨论现有温排放数值计算模型的发展以及存在的问题,主要包括温排放系统模式的选取和模型边界控制等。认为三维数值模型在一定程度上代表温排放数值模拟的发展方向,并应考虑斜压效应,且将水动力场与物质扩散场耦合求解。

The advances in numerical simulation of thermal discharge of worldwide heat or nuclear power plants in coastal areas in recent years were reviewed.The development situations and some basic issues of the existing numerical models for the thermal discharge were highlighted,mainly including selection of turbulent modes of the thermal discharge and control of model boundaries.A conclusion is drawn that 3D numerical models are regarded to represent the development tendency of those for the thermal discharge to a certain extent.The oblique pressure effects should be considered.The hydrodynamic fields and the diffusion fields of matters should be coupled for the solution.
