The paper describes entrainment into sprays produced by a consumer product aerosol dispenser that allows substitution of water for volatile organic compound solvents and air for hydrocarbon propellants. Experimental data are analyzed, along with measured momentum rate data that were aquired as part of the study. The analysis shows that dimensionless entrainment by sprays produced using this type of atomizer is accurately predicted, using: (1) the distance along the spray acix; (2) the exit orifice diameter; (3) the spray momentum rate at the exit orifice; (4) the density of the entrained air; (5) the entrained gas mass flow rate; (6) the mass flow rate of liquid exiting the dispenser; and (7) the entrainment whose value is 0.15 plus or minus 0.056.
