ABSTRACT:
A foam dispensing system for a foamable liquid has a means for producing a spray of droplets in which the spray of droplets has key parameters of: the number averaged mean diameter and the mean axial droplet velocity. The foam dispensing system also has a foaming nozzle connected to the means for producing a spray of droplets that is placed in fluid communication with the spray of droplets. The foaming nozzle has a screen which has a plurality of screen openings having a mesh range from 30 to 60 openings per linear inch. Key parameters of the screen are: the percent open area is from about 35% to 60% and the screen openings are larger than the number average mean diameter of the spray of droplets. When the mean axial droplet velocity is at least 8 m/s, the spray of droplets is transformed into a foamed spray as the droplets pass through the plurality of screen openings.
