本文的工作为建立一套高效的旋流发生器内气液两相流动实验装置做了初步的研究。采用单相流计算流体动力学（CFD）方法，研究了螺旋管、单螺旋带和双螺旋带3种不同旋流元件对垂直管内流动的影响。根据在旋流元件下游一定距离处的平面中的速度流线和旋流强度的轮廓的观察，选择将用于进一步研究的旋流元件。基于这些参数，选择了双螺旋带，因为它能够产生更强的旋流，这将有利于在线分离器中的气液分离。
This work is a preliminary study to develop an effective and efficient experimental facility on the gas-liquid flow in the swirl generating device. The flow in a vertical pipe packed with three different swirl elements: coil, single helical tape and double helical tape were studied using the single phase Computational Fluid Dynamics (CFD) simulations. The selection of the swirl element which will be used in the further study was made based on the observation in the velocity streamlines and the contour of the swirling strength in the plane located at a certain distance downstream the swirl elements. Based on those parameters, the double helical tape was selected due to its ability to generate a stronger swirling flow which will be beneficial for the separation of gas and liquid in an inline separator.
