Abstract

Theoretical development of the principles of fluid mechanics and vortex flows has been presented in an effort to mathematically analyze the vortex amplifier. Certain simplifying assumptions were made in order to obtain solutions to the Navier Stokes equations. An optimized vortex valve was constructed based on theory and semi-empirical relationships. Three exit nozzles were tested and analyzed. Orifice one was able to obtain complete supply shutoff and a flow turndown of 1.9. Characteristic performance curves of the amplifier describe its shutoff capabilities and operating region.
