ABSTRACT:
A converging/diverging venturi assembly positioned in a subsonic fluid flow stream for producing a supersonic flow velocity in the downstream diverging section with a pressure pickoff system that is located adjacent a minimum static pressure location just prior to a point where shock waves begin to form. The low pressure in the supersonic region in front of the shock wave may be utilized for reducing the boiling temperature of a fluid in a boiler by porting a tube from the low pressure venturi to the boiler, thus improving the heat transfer characteristics of the boiler where the boiler is used for a heat sink for heat sources in a mobile vehicle.
