摘要

对模块化直接空冷单元的研究是空冷凝汽器研究的一项基础性工作。建立某直接空冷单元流动和传热的数值模型

利用计算传热学(NHT)软件FLUENT

研究简单风机模型与详细风机模型对直接空冷单元数值模拟结果的影响。结果表明:详细风机模型可反映空冷单元管束内外部空气速度场和温度场的实际情况。因此

对空冷单元及空冷岛进行模拟和分析时

应采用详细的风机模型。

Abstract

It is a basie work for the study on modularized unit of direct air-cooled condenser(ACC).Establishing a numerical model of flow and heat transfer for one direct air-cooled unit

and using the numerical heat transfer software called FLUENT

the influence of fan models

namely simple fan model and detailed fan model

upon the simulation results of air-cooled unit has been studied.Results show that the detailed fan model can reflect the real situation of the direct air-cooled unit.Therefore

during the time of carrying out simulation and analysis for air-cooled unit and air-cooled island

the detailed fan model has to be adopted.
