The jet fountain also includes a surface disruptor that includes a body, a water inlet, a valve, a fluid outlet, and a trajectory adjuster emanating a second stream of fluid from the fluid outlet. The second stream of fluid may be positioned to intersect the first stream of fluid and perturb its laminarity. By adjusting a valve controlling the force and volume of flow of the second stream and/or by adjusting the trajectory adjuster, the intersection of the first and second streams may be modified and, therefore, the laminarity of the first stream may be modified. By disrupting the laminar surface of the first stream, light introduced into the first stream may be caused to refract outward from the first stream and thus enhance illumination of the first stream.

  • Patent number: 7798430
    Abstract: A fuel injection nozzle is formed with a nozzle hole group including at least two individual nozzle holes, which are disposed close to each other. Fuel is injected through the nozzle hole group. In at least one combination of two adjacent individual nozzle holes included in the same nozzle hole group, at least one of the two adjacent individual nozzle holes is configured such that each of the at least one of the two adjacent individual nozzle holes has a diameter, the diameter increasing only toward a corresponding adjacent one of the two adjacent individual nozzle holes along a direction from an inside to an outside of the each of the at least one of the two adjacent individual nozzle holes, and the diameter being maximized at an outer opening of the each of the at least one of the two adjacent individual nozzle holes.

  • Patent number: 7762476
    Abstract: The present technique provides a system and method for improving atomization in a spray coating device by internally mixing and breaking up a desired coating fluid prior to atomization at a spray formation section of the spray coating device. An exemplary spray coating device of the present technique has an internal fluid breakup section comprising at least one fluid impingement orifice angled toward a fluid impingement region. In operation, the internal fluid breakup section forms one or more fluid jets, which impinge one or more surfaces or one another in the fluid impingement region. Accordingly, the impinging fluid jets substantially breakup particulate/ligaments in the coating fluid prior to atomization. The resulting spray coating has refined characteristics, such as reduced mottling.

  • Patent number: 7670440
    Abstract: A nozzle (54) for cleaning a gas turbine unit (1) during operation. The invention further relates to a method for washing a gas turbine unit (1) during operation. The nozzle (54) is arranged to atomize a wash liquid in the air stream in an air intake (2) of the gas turbine unit (1) and comprises a nozzle body (40) comprising an intake end (41) for intake of said wash liquid and outlet end (55) for exit of said wash liquid. The nozzle further comprises a number of orifices (42, 46; 42, 46, 60) that are connected to the outlet end (55) and respective orifice (42, 46; 42, 46, 60) is arranged at a suitable distance from a center axis (49) of said nozzle body (40), whereby the local density of the injected wash liquid in a desired area can be increased with preserved droplet size and thereby the efficiency of the cleaning process can be significantly improved at the same time as the risk for damaging the components in the gas turbine unit is significantly reduced.

  • Publication number: 20090314500
    Abstract: Apparati for generating a mist are disclosed. One apparatus is disclosed, which has an elongate hollow body (12) and an elongate member (14) located within the body (12). A transport fluid passage (16) and a nozzle (32) are defined between the body (12) and the elongate member (14). The transport fluid passage (16) has a throat portion of reduced cross-sectional area and is in fluid communication with the nozzle (32). The elongate member (14) includes a working fluid passage (26) and one or more communicating openings, such as for example, bores, annuli, and combinations thereof, (30) extending radially outward from the working fluid passage (26). The openings (30) permit a working fluid (e.g. water) to be passed into the transport fluid passage (16), whereupon the working fluid is subjected to shear forces by a high velocity transport fluid (e.g. steam). The shearing of the working fluid results in the generation of a mist formed from droplets of substantially uniform size.

  • Patent number: 7472845
    Abstract: An orifice disc for a fuel injector includes two orifices that provide a desired interaction between two fuel flows to increase fuel atomization and improve combustion performance. The orifice disc includes a first orifice and a second orifice that are disposed at an interaction angle relative to each other. The orifices are orientated relative to each other such that fuel flow exiting the outlets impinges on each other to further reduce the size of fuel droplets. Large dramatic changes in momentum caused by the impingement of fuel flows disintegrates fuel droplets into much smaller finer fuel droplets that provided enhanced atomization.

  • Patent number: 7389951
    Abstract: A misting spray nozzle includes a hollow body having an interior wall descending from an upper end to a lower end. The interior wall tapers toward the lower end to form a choke. A channel section provides two fluid paths descending from an upper central aperture. A turbine is sized and shaped to fit closely within the choke and has spiral grooves on its outer surface. The turbine attaches to the body at its upper end and has a cone-shaped opening at its lower end. A conical core is sized and shaped to fit closely within the cone-shaped opening and has grooves spiraling in an opposite direction on its outer surface. The core is attached at its upper end to the turbine. The two sets of spiral grooves define a pair of intersecting fluid control paths that meet at the lower end of the body to create a dense mist.
