Abstract

A nozzle with an inlet and an outlet, including a shell, a rotor element located inside the shell and configured to be driven into rotation about a rotation axis upon being subjected to the action of a fluid flow entering the nozzle inlet and circulating through the nozzle towards the nozzle outlet, and a stationary splitter element located inside the shell, downstream of the rotor element, along the passage of the fluid flow. The rotation axis coincides with a main direction along which the fluid flow projects from the nozzle outlet. The rotor element includes peripheral helical grooves configured to permit passage of the fluid flow and cause rotation of the rotor element. The splitter element includes splitter openings communicating with a downstream end of the peripheral helical grooves to cause splitting and modulation of the fluid flow as a function of rotation of the rotor element with respect to the stationary splitter element. The nozzle further includes flow conditioning elements located inside the shell, downstream of the splitter openings, and configured to cause recombination of the fluid flow, split and modulated by the splitter element, into a pulsatile jet of fluid projecting from the nozzle outlet along the main direction that coincides with the rotation axis.
