摘要
针对海上核电平台的温排放在船体周围外域扩散问题,开展温度场的三维数值模拟方法研究。采用有限体积法和雷诺平均的方法对海上核电平台船的温排水在船体外域流场中的温度扩散进行数值模拟,研究网格数量、时间步长和缩尺比对数值模拟结果的影响,通过不同网格数量、不同时间步长不同缩尺比的数值仿真,找到核电平台温排水数值模拟的最佳网格数量、时间步长和主缩尺比参数。
A three-dimensional numerical simulation method for the temperature field of floating nuclear power plant was presented to solve the thermal discharge problem around the ship hull.The finite volume method combined with Reynolds average method was used to simulate the thermal diffusion in the external flow field.The influence of the number of grids,time step and scale ratio on the numerical simulation results was studied.Through the numerical simulation of different grid number,time step and scale ratio,the optimal number of grids,time step and scale ratio parameters for the numerical simulation of thermal discharge of floating nuclear power plant were found.
