Abstract
The velocity profiles of a circular jet and a square jet with initially laminar boundary layer were measured from the jet exit to about 45 diameters d (or equivalent diameters De) downstream with a single hot wire probe to verify a new quantification method for valvular regurgitation and lesion size. The onset of self-similarity for centerline local mean velocity is found to be about 6d with initial laminar velocity condition. Velocity measurements of valvular regurgitation jets, for that matter, should be taken at a minimum distance of 6d.
