An experimental analysis of the turbulent flow downstream of a plane symmetric sudden expansion
Abstract
The present paper is concerned with the turbulent flow of water downstream of a plane symmetric sudden expansion. The detailed investigation of the flow were carried out in a two-dimensional plane duct. The measurements were performed by means of a laser anemometer system. The measurements of the velocity and turbulence intensity for various downstream stations are reported. The experimental work analyzes the behavior of the flow through a symmetric sudden expansion and should help to get some insight into the flow phenomena involved. A conclusion can be drawn from these results with respect to the flow field, dissipation and turbulence transfer. The results of the investigation allow a comparison to be made between the physical reality and the theoretical models.
