弯管中段塞流的数值模拟

Numerical Simulation of Slug Flow in Bend

以中心角为90°的弯管作为模拟模型,在压力0.15MPa、气体质量流量为0.912 6g/s的条件下,分别选取4组不同的液体流量0.27、0.40、0.53、0.80kg/s,采用FLUENT软件对每一种工况进行了数值模拟。通过数值模拟结果,对每一种工况下的弯管处流体流动的特性进行了分析,得出了不同液体流量下弯管段塞流的基本规律及特性。

The center angle of 90°as a simulation model of the elbow,under the pressure of 0.15 MPa,the gas mass flow rate of 0.912 6g/s condition,it selects four different liquid flow：0.27,0.40,0.53,0.80kg/s,and each condition is simulated using the FLUENT software.By numerical simulation results,it analyzes the fluid flow characteristics at the elbow at each of the conditions,and get the basic law and characteristics of elbow slug flow under different liquid flow.
