摘要：

摘要：  试验研究了带有复杂入口管的积液型两相流分液器在不同干度和质量流量条件下的分液均匀性.结果表明：当干度增大时，分液器的分液均匀性下降；当质量流量增大时，分液器的分液均匀性得到改善；各工况下分液器分液的流体质量流量标准偏差（STD）的平均值为2.80%.同时，对复杂入口管进行了计算流体动力学模拟，提出了一种能够有效降低入口管形式影响的新型双筒体型分液器，并通过试验加以验证.验证试验结果表明，在各工况下，双筒体型分液器分液的STD的平均值为2.36%，比积液型分液器的分液均匀性提高了15.7%.

Abstract:

Abstract： This paper studied the distribution performance of a reservoir distributor with complex inlet tube under different conditions. The result shows that the performance is improved with the increase of mass flow rate or the decrease of quality. The average STD is 2.8%. A simulation modeling was made. A new double-barrels distributor was proposed to reduce the influence of the complex inlet tube. The average STD is 2.36%, which is 15.7% better than the original sample.

Key words: distributor, computational fluid dynamics (CFD) simulation, inlet condition, double-barrels
