Abstract:

This paper summarizes the results of investigations in the M, I, T. Unsteady Flow Water Tunnel of accelerated and decelerated flow through uniform conduits and orifices in conduits. In the uniform conduit shear and turbulence is generated through boundary layer friction and is essentially uniform along the duct. The orifices cause separation and jet formation with accompanying high shear and turbulence which varies along the duct as the jet diffuses and the turbulence is dissipated.
