  • Patent number: 5213260
    Abstract: A nozzle which produces laminar fluid flow, which may be used in fountains and water displays, is disclosed. The nozzle disclosed reduces the turbulence of the fluid flowing through the nozzle by using a material which has randomly-arranged filaments for dividing the velocity components of the incoming fluid stream into smaller components. Some of the velocity components cancel each other thereby presenting a more uniform velocity profile, reducing the turbulence of the fluid, and allowing laminar flow at higher flow rates than would otherwise be possible.
