A Visual Study of the Flow Model in the Later Stages of Laminar-turbulent Transition on a Flat Plate

A number of aspects of transition from laminar to turbulent flow were investigated on a flat plate with free stream water velocities between .75 feet per second and 1.2 feet per second. The study was primarily visual, using dye techniques, although some measurements were made using a hot film anemometer. Also investigated were the later stages of natural transition. Dye patterns associated with the chain of events leading from laminar to turbulent flow in natural transition were analyzed. (Author).
