液固两相射流中304不锈钢冲蚀行为研究
Investigation of particle impact on 304SS under the liquid-solid two phase flow
Abstract
随着社会工业、经济的发展,对能源的需求量日益增加,与此同时也造成了日益严重的环境污染问题。因此,能源结构的调整显得越发重要与急迫。核能具有环保、清洁、能量密度高的特点,弥补了新能源能量密度低的不足,避免了传统化石能源对环境的危害。自1954年世界上第一座核电站并网发电以来,核能得到了较大的发展,然而其安全性影响了核电持续、稳定、长远的发展。 在核电站正常运行时,颗粒状腐蚀物如铁屑、铜屑、细砂等,于二回路、三回路中与流动的流体形成液固两相流。液固两相流会对管道壁面进行磨损-腐蚀行为,导致材料的损耗、设备的失效,带来严重的安全问题。本文对颗粒与壁面的碰撞中,颗粒行为、颗粒的属性变化和金属表面特征... With the rapid industrialization, the demand for energy is increasing day by day. Meanwhile, the environment pollution is more serious than ever before. Therefore, the adjustment of energy structure becomes more and more important and urgent. Nuclear energy which has the characteristics of environmental protection, clean and high energy density makes up for the low energy density of the new energy...
