Clarification of Ejection and Sweep in Rectangular Channel Turbulent Flow

The experimental study has been carried out to investigate the behavior of ejection and sweep events in a rectangular channel turbulent flow. The channel is a 1800 mm long vertical channel with a cross sectional area of 100 mm and 20 mm. The events are studied by obtaining velocity components of the flow by using the ultrasonic measurement method (UVP). This paper clarifies the capability of the UVP for investigating the sweep and ejection events.Copyright © 2010 by ASME
