A REVIEW ON SWIRLING FLOW USING VISUALIZATION TECHNIQUES: PART 1. THE CIRCULAR TUBES

摘要

Swirling flows are found in very wide range of applications, for examples, cyclone separators, spraying machines, heat exchangers and jet pumps, ect. This study deals with many visualization techniques to study on swirling flow. These techniques are related to oil films methods, smoke, dye liquids, liquid crystal, stroboscope light, smoke wire, white light, naphthalene sublimation, Present work has handled single, annular, carved tube, swirl expansion and swirl wake using several visualization methods in the horizontal and vertical circular tube.
