Two-dimensional vortex ring studies
This project aims to conduct a study on two-dimensional vortex rings formation. The generation of the vortex rings was conducted in the Water Tunnel Facility using a rectangular and a circular orifice. Both the height of the rectangular orifice slot and the diameter of the circular orifice slot were...

The generation of the vortex rings was conducted in the Water Tunnel Facility using a rectangular and a circular orifice. Both the height of the rectangular orifice slot and the diameter of the circular orifice slot were designed to be 40 mm.
