摘要
选取某电厂600MW机组凝汽器水侧流场进行数值模拟,研究流体的流动状况。模拟结果显示,凝汽器进口水室内存在涡旋,涡旋的存在增加了流体的流动阻力,使流动恶化,流量分布的不均匀,严重影响了设备的换热性能。在使用过程中,应采取措施减小涡旋,计算结果可以为凝汽器设计和改进提供参考。
The condenser water flow field of the 600MW power station is simulated,to study fluid flow conditions. Simulation results show that the before of the condenser water,the vortices increase the flow resistance of the fluid,aggravate flow conditions,affecting the operation of the equipment's safety and economy. Therefore,it is necessary to take suitable measures to alleviate the influence of flow deflection on the condenser. The computation results are helpful to reasonable design of power plant condensers.
