Mixing Nozzles for Liquid-Fuel Rocket Motors

Abstract

When two immiscible liquids are to be used as rocket propellants it may be advantageous to spray them as a fine emulsion into the combustion chamber. Experimental work has been carried out on nozzles in which two liquids are caused to form an emulsion by means of rotational forces resulting from the pressure drop in various swirl nozzles. Modifications of well known types of swirl atomizers have been tried, but the best results have been obtained with a nozzle designed specially for mixing. Proposals are made for determining whether mixing nozzles give results which are better than those obtained by conventional methods of injection.
