摘　　要：采用大涡模拟的方法,对威力巴流量计在气固两相流中的特性进行了数值模拟。初步揭示了连续相中固粒在检测杆截面周围的分布特性以及不同粒径的固体颗粒对检测杆碰撞而产生的磨损量。In this paper,LES technique was applied to investigate characteristics of the gas- solid two phase flow over the Verabar flow- meter＇s detection rod. Particles＇ distribution features surrounding the detection rod were numerically predicted. Erosion effects of particles with different diameters on the detection rod due to collisions were then numerically analyzed.

关 键 词：气固两相流 大涡模拟 分布特性 碰撞与磨损
