摘要

基于Ansys cfx软件

采用标准k-ε湍流模型和可升级壁面函数法对超(超)临界1 000MW机组给水泵内流场进行三维定常湍流计算

获得了叶轮、导叶等关键部件内部流场的速度、压力分布。通过分析数值计算结果预测给水泵性能

得到给水泵扬程预测值与试验值相对误差在1.8%～7.8%范围

给水泵效率预测值与试验值相对误差在3.5%～6.3%范围

预测值与试验值基本吻合。

Abstract

Based on analysis of the ANSYS CFX software

and adopting the standard k-ε turbulence model and the upgradable wall-surface function metod

a three-dimensional steady turbulent flow field in the feed-water pump of boiler equipped with 1 000 MW unit has been calculated

the velocity and pressure distribution of flow field within the main parts

namely impeller and guide vanes

being achieved.Analysis of numerical calculation results and the predicted characteristic curves of the feed-water pump show that the relative error between the predicted discharge head of said feed-water pump and the tested value is in a range of 1.8%~7.8%

and the relative error between the predicted efficiency of feed-water pump and the tested value is in a range of 3.85%~6.3%

being basically tallied.
