摘要
利用计算流体力学软件Fluent对90°弯管中的管道螺旋流进行模拟,通过建模和数值计算,研究了弯管中螺旋流的生成、发展和衰减规律。结果表明切向进流角度60°时切向流速最大,这有利于清除弯管中的沉积杂质,同时证明弯管有很好的继旋作用。
The spiral flow was simulated in the 90° bend pipe by using CFD software Fluent. Through the modeling and numerical calculation, it displayed the formation, development and attenuation of spiral flow. The results showed that when the angle of inlet was 60°, the tangential velocity was the highest, which was beneficial for removing sedimentary impurities in bend pipe, which also showed that bend pipe worked well for flow convection.
