Liquid spiral vortex discovered

In many plumbing and pipework systems in general, there are junctions and connections to move liquids such as water in different directions, but have you ever thought about what happens to the water in those fluid intersections? A team of researchers from Okinawa Institute of Science and Technology Graduate University (OIST) and collaborators found an unexpected spiral vortex phenomenon that occurs in the intersections of cross-shaped devices when liquid flows through the channels in a particula
