摘要 分别采用Euler-Euler和Euler-Lagrange两相流模型对离心式纸浆泵进行了数值模拟,考虑叶轮间隙流动,预测了泵的磨损特性.欧拉方法采用Particle两相流模型,壁面的磨损程度与固相体积分数和滑移速度相关.拉格朗日模型采用Finnie磨损预估模型.开式叶轮纸浆泵多个流量工况的计算结果显示,欧拉方法预测的叶片和前盖板在设计流量下磨损严重,压水室在小流量工况时磨损严重.拉格朗日方法显示叶片和前盖板的磨损最严重,磨损率随流量增加先增大后减小,压水室和后盖板的磨损率逐渐减小.2种模型预测的叶轮与前盖板磨损严重的现象与实际吻合;拉格朗日模型可定量分析磨损部位和磨损程度等特性.本研究为纸浆泵的两相流数值模拟和磨损特性研究提供了一定参考.

Abstract: Euler-Euler and Euler-Lagrange two-phase model was applied to simulate the turbulent flow in the pulp pump and to predict the erosion characteristics considering the impact of tip clearance. Euler multiphase model use Particle model to analyze two-phase flow, the wall wear was mainly affected by the slip velocity and the fraction of volume of solid particles. Lagrange multiphase model was applied to predict the wear quantity based on Finnie erosion model. The result of pulp pump′s open impeller under different discharge conditions show that, the Euler model predict blade and front cover wear seriously under the design flow rate, case wear seriously under the small flow rate. The Lagrange model revealed the blade and front cover wear seriously, found the wear rate of blade and front cover increased and then decreased with the discharge rising, the wear rate of back cover and case decreased gradually. These two model predict the impeller and front cover are badly worn,which coincide with the actual phenomenon. Lagrange model can analyze the wear positions and degree quantitatively. This study can provide a reference for the research of pulp pump two-phase flow and erosion prediction.
