摘　　要：针对火力发电厂粉煤灰气力输送时经常发生管道弯头磨穿的情况,设计了特殊几何结构的防磨弯头。选取两种不同几何结构的弯头,对其内部的气固两相流流场进行了数值模拟,并对其防磨特性进行了比较分析。According to the condition that the pipe bend wear often occurs in the thermal power plant fly ash pneumatic conveying,a special geometry of the wear resistant elbow was designed.Two kinds of different geometry bend were introduced,the gas solid two phase flow were numerically simulated,and the wear characteristics were comparatively analyzed.

关 键 词：弯头 数值模拟 气力输送
