Abstract
An apparatus for creating a fine liquid mist includes a container capable of holding fluid; one of a perforated basket and a porous bag disposed in the container; a liquid supply connector connected to the container; a mixing chamber connected to the container; and at least one convergent/divergent nozzle connected to the mixing chamber. A method of forming an effervescent fine liquid mist includes mixing liquid and chemical reactant to form non-toxic, noncombustible gas bubbles; mixing the liquid and the gas bubbles to form a two-phase fluid flow; and directing the two-phase fluid flow through at least one convergent/divergent nozzle.
Claims5
A method of forming an effervescent fine liquid mist, comprising:
- mixing liquid and chemical reactant to chemically form non-toxic, noncombustible gas bubbles;
- mixing the liquid and the gas bubbles to form a two-phase fluid flow;
- directing the two-phase fluid flow through at least one convergent/divergent nozzle;
- expanding and bursting the gas bubbles in a diverging section of the nozzle;
- and
- shearing the liquid to form a liquid mist.
