Abstract:
A method of creating an aerosol, comprising:forcing a liquid through a channel of a feeding source in a manner which causes the liquid to be expelled from an exit opening;forcing a gas through a pressure chamber in a manner which causes the gas to exit the pressure chamber from an opening positioned in front of a flow path of liquid expelled from the exit opening of the feeding source;wherein a stable liquid-gas interface is maintained and the liquid forms a stable capillary jet between the feeding source exit opening and the opening of the pressure chamber;wherein fluctuations in dynamic forces exerted by the gas do not exceed the surface tension forces on surface of the liquid in the pressure chamber; andallowing the microjet to exit the pressure chamber opening and split into drops by effects of instability.
