Abstract:

It is known that the presence of swirl in a flow stream can affect heat and mass transfer rates, and pulsatile flow has important aspects in physiological studies and in non-stready turbulent flows. The investigation consisted of an experimental study of the generation and decay of swirling flow in a duct utilizing a new method of swirl generation, and the measurement of the fluctuations imposed on the steady turbulent flow profile by pulsing the flow in a duct. New results were obtained that gave insight into the effects of swirling and pulsing the flow through an asisymmetric duct.
