摘要
本文应用Fluent软件对喷油螺杆式空气压缩机第一级油气分离器内的气液两相流流场进行了数值模拟。在数值模拟的基础上,对油气分离器流场进行了机理分析,指出气流在壁面上的碰撞过程对分离效果具有重要影响,并据此提出新的改型设计方案。随后进行的工程试验证明数值模拟所用的计算模型是有效的,相应的机理分析也是正确的。改型设计方案的分离效率明显高于原设计方案。
The flow field inside an oil-gas separator are simulated with software Fluent. Based on the analysis of the two-phase flow field, the authors find, beside the centrifugal force, the collision plays an important role in the oil-gas separation. Modifications of the separator design had been made according to this analysis. With engineering tests, the numerical model and the correspondent analysis are proved to be effective in the engineering design of oil-gas separators. The oil carry-over rate is greatly reduced in the modified separator.
