摘要

空气凝汽器由模块化的空冷单元组成。建立了某135 MW机组直接空冷岛空冷单元流动和传热数值模型

利用计算传热学(NHT)软件FLUENT

对不同环境风速下空冷单元进行数值模拟。经对直接空冷单元外部空气的速度场、温度场的模拟、分析和研究表明

风机风量为370.0 m3/s

空冷单元散热量为13.8 MW

即当模拟风量低于设计风量7.57%时

模拟散热量高于设计值2.76%。

Abstract

The air cooled condenser(ACC) is composed of modularized air cooled elements.The flow and heat transfer model of an air cooled element used for simulation of ACC island for 135 MW unit has been established.By sing the numerical heat transfer(NHT) software named FLUENT

the numerical study on the performance of air cooled element under different environmental wind speed has been carried out.Through simulation

analysis

and investigation of the velocity field and the temperature field of air flow outside the direct air cooled element

it shows that the air flow rate is 370.0 m3/s

the radiating heat from the air cooled element is 13.80 MW

i.e.in the case of simulated air flow rate being lower than that of designed value by 5.57%

the simulated air flow rate is still higher than that of designed value by 2.76%.
