摘要

影响空冷凝汽器换热性能的主要因素是环境大风所造成的热风回流或热风再循环。建立了某135MW机组直接空冷凝汽器流动和传热的数学模型。利用计算传热学软件Fluent

对夏季汽轮机考核工况(TRL)下空冷凝汽器的性能进行了数值模拟

即对直接空冷凝汽器外部空气的速度场、温度场进行模拟、分析和研究

为直接空冷系统的优化设计提供帮助。

Abstract

The main factor affecting the heat-exchanging performance of direct air cooling condenser is backflow or recirculation of the hot air resulted from the ambient strong wind. A mathematical model of flow and heat transfer in direct air cooling condenser for a 135 MW unit has been established. By using a heat transfer software Fluent

the numerical simulation of direct air cooling condenser's performance under condition under turbine rated load (TRL) in summer has been carried out

i.e. the velocity field and temperature field of air outside the air cooling condenser have been simulated

analyzed

and studied

providing with help of optimizing design of the direct air cooling system.
