A nozzle is provided for increasing the velocity of a fluid flowing therethrough, such as steam or other working fluid. The nozzle generally includes a body portion with a conical helical passage formed through the body portion to define an unlet port and an outlet orifice. The passage diameter can decreases continuously from the inlet port to the outlet orifice. Further, the conical helical passage can be a right-handed helix. To aid in manufacture and repair, the body can be divided into quadrants, where each plane of division passes through the center axis of the body portion. The present nozzle can be, for example, inserted into a steam turbine nozzle box as s retrofit for increasing the velocity of the steam incident on the turbine blades to increase turbine efficiency.

A liquid nebulizer (1) for medical uses wherein a dome-shaped body (10) is shaped symmetrically with respect to a first frontal median plane (M) and to a second sagittal median plane (N) intersected in a central axis (A); the dome-shaped body (10) being developed along the axis (A) between a base portion (100) and an upper truncated portion (102) provided with a cavity (1020); at least two channels (12)(12′) being provided, each of which shaped to access the cavity (1020) through a respective hole (120)(120′) arranged at a given distance from one of the first frontal median plane (M) and second sagittal median plane (N).

A fog injection nozzle able to generate a swirling cone of fog. The nozzle includes an internal cavity into which a pressurized liquid and a pressurized gas are introduced. The pressurized liquid is introduced into the cavity via a central axial duct of a cylindrical block and the pressurized gas is introduced into the cavity via a plurality of axial through holes disposed about the central axial duct. The axial through holes and radial arms are arranged such that a mixture of the liquid and gas inside the cavity is asymmetrically deflected by the radial arms to cause a swirling tangential component to appear in the conical flow of fog discharged from the nozzle.

The disclosure relates to a nozzle for a device for the dermo-cosmetic treatment of dark skin spots by cyto-selective cryotherapy comprising a spray jet supplied by a tank of pressurised liquified cryogenic gas. The nozzle comprises an upper ring for connecting to a shell, extended by a central body of which the side wall which narrows downwards has longitudinal openings and delimits a gas expansion chamber communicating with a frustoconical dispersal conduit arranged inside an end piece to be applied to the skin and opening to the outside through a discharge port.

A method of controlling the spray droplet size of a spray nozzle apparatus, in particular for the manufacturing of food powders, delivered to the spray nozzle comprises the following steps: a) providing a paste of a product to be sprayed by a spray nozzle; b) continuously determining the shear viscosity (η) of the product paste delivered to the spray nozzle; c) determining the mass flow rate (Qm) of the product paste delivered to the spray nozzle; d) determining the static pressure (P) of the product paste delivered to the spray nozzle; e) determining the density (p) of the product paste delivered to the spray nozzle; f) delivering the data obtained in steps b) to e) to a control device comprising a computer and a memory; g) calculating control data for adjusting the spray nozzle on the basis of the data obtained in steps b) to e) and on nozzle geometry parameters stored in the memory; h) sending the control data as control signals to a control means of the spray nozzle and adjusting the spray nozzle accordingly.
