Abstract
A spray nozzle designed to produce a spray or mist containing a high concentration of bubbles. Such a spray is particularly useful in mixing liquid fuel and air for burning within a combustion chamber, as for example in a gas turbine engine. The novel design includes a pair of swirl chambers generally axially aligned within the nozzle. Fuel or other liquid enters the first or forward swirl chamber in a generally tangential and laminar flow pattern, passes into the second or rearward chamber through an interconnecting orifice. Violent liquid and air mixing occurs in the second chamber and the mixture is then expelled as an aerated spray through the interconnecting orifice, the first chamber and a discharge orifice.
