A vortex venturi for reverting antimisting fuel propertiesThe level of degradation of antimisting fuel polymers such as FM-9 which must be accomplished in order to use antimisting fuel in existing engines may require the use of cavitation. The hydrodynamic shear produced by the collapse of vapor bubbles is capable of producing more splitting of polymeric molecules than mechanically-induced shear. A program has been carried out to investigate the possibility of using a cavitating venturi with rotating flow as a fuel reverter. This investigation included the effects of a swirl-inducing twisted tape upstream of the throat, inlet pressure, recovery pressure ratio and a pintle for varying throat area. A correlation of the data was produced, system concepts for using the vortex venturi were investigated and problem areas were delineated.
