摘要
借助数值模拟方法对Ω型气液分离器的内部流场状态进行预测,计算采用二维雷诺时均N-S方程,湍流模型采用标准k-ε模型,获知分离器内部流场分布特性,对不同间隙的Ω型气液分离器性能进行研究,并制作模型进行风洞实验,验证理论计算结果,得到该型气液分离器的阻力及效率特性。研究表明,Ω型气液分离器具有较高的气液分离效率,并且分离效率与叶片间距有很大影响,采用的Ω型叶片间距为18.2mm时,平均分离效率在90%以上。
With the help of a numerical simulation method,predicted was the status of the flow field inside a Ω type gas-liquid separator.In the calculation,the two-dimensional Reynolds time-averaged N-S equation was adopted,and the standard model has been used as the turbulent flow model to obtain and understand the distribution characteristics of the flow field inside the separator.Moreover,the performance of the separator with different clearances was studied and a model was fabricated to conduct a test in a wind tunnel.The theoretical calculation results were verified,and the resistance and efficiency characteristics of the separator,obtained.It has been found that the separator has a relatively high gas-liquid separation efficiency and the blade spacing exercises a very big influence on the separation efficiency.When the Ω type blade spacing is 18.2 mm,the average separation efficiency can reach over 90%.
