Abstract: A vortex spray generating system that comprises a discharge channel and at least one inlet channel. The discharge channel and the at least one inlet channel are disposed with respect to one another such that the at least one inlet channel is capable of providing a tangential feed of fluid into the discharge channel sufficient to generate a vortex and spray pattern. A method of generating a vortex in a pressurized fluid so as to deliver the pressurized fluid as a spray. The method comprises providing a vortex spray generating apparatus comprising a discharge channel and at least one inlet channel, and introducing a tangential feed of fluid through the at least one inlet channel into the discharge channel sufficient to generate a vortex and spray pattern. The at least one inlet channel is disposed such that it is perpendicular to the discharge channel or angled with respect to the discharge channel.
