Flow Rate along the Length of the Swirling Vortex Axis at an Intake

Year 2021, Volume: 32 Issue: 4, 11013 - 11027, 01.07.2021

Abstract

In this study, the characteristics of the flow in the region of swirling vortex are examined. The potential flow model based on the summing infinite number of spherical sinks along the vortex core is introduced to predict the flow field and the flow rate along the vortex axis. The flow towards the swirling vortex core has considerable effects on the radial velocity distribution within the ambient fluid flow region near the intake. The agreement between available test data relating to the radial velocity and the method introduced in this study is found to be satisfactory.
