University of Chicago physicists working in the nascent field of experimental vortex dynamics have, with unexpected help from a Sharpie marker, achieved the first measurements of an elusive but ...

These experiments examines the flow field in the region where a moving wall slides under a stationary one. This produces an interesting flow phenomena with relatively simple generation geometry. The ...

Marked departures from inviscid flow were found when swirling water was discharged downwards under pressure through a Perspex conical nozzle. A boundary layer of forced vortex motion formed on the ...
