摘要

采用Fluent软件对某火电厂2×1 000 MW机组直接空冷系统流场进行数值模拟

在来流风速为7m/s、风向角为0°、环境温度为30℃的条件下

计算加高挡风墙对空冷岛温度场、热态流场和热回流率的影响。结果表明:适当增加挡风墙高度

可使空冷岛底部高温区域明显减少

热回流率降低;综合考虑增加挡风墙高度对直接空冷系统流场的影响以及建筑材料成本

挡风墙在原有设计值的基础上以增加2~3m为宜。

Abstract

The Fluent software was applied to simulate the flow field of direct air-cooled system in 2×1 000 MW unit.Moreover

the effects of heightening the windbreak on such parameters as the temperature field

hot flow field and thermal recirculation rate of the air cooling island were investigated

under conditions with facing velocity of 7m/s

wind direction of 0°and ambient temperature of 30℃.The results show that

appropriately heightening the windbreak can obviously reduce the high-temperature regions in the end portion of the air cooling island.Comprehensively considering the effects of heightening the windbreak on the flow field of the direct air-cooled system

as well as the building material cost

increasing the windbreak height by 2~3mis suitable.
