Vortex Formation in a T-Junction
Flow visualization was used to study the jet in a erossflow problem in the bifurcating pipe flow of a T-junction. The visualizations revealed a great variety of vortex phenomena and — structures generated by the complex interaction between jet and crossflow. This paper reports on some of these and offers a qualitative insight into the very complicated three-dimensional nature of flow fields in a T-junction.
