Abstract
Leakage components are described herein. The leakage component includes a first tubing housing and a plurality of leakage ports. The first tubular housing defines a first flow path between a first end portion and a second end portion. The plurality of leakage ports are formed in the first housing and in fluid communication with the first flow path. The fluid flow through the plurality of leakage ports is configured to entrain ambient air into the fluid flow exiting the plurality of leakage ports to decelerate the fluid flow.
Claims20
A leakage component, comprising:
- a tubular first housing defining a first flow path between a first end portion and a second end portion;
- and
- a plurality of leakage ports formed in the first housing and in fluid communication with the first flow path, wherein fluid flow through the plurality of leakage ports is configured to entrain ambient air into the fluid flow exiting the plurality of leakage ports to decelerate the fluid flow, a profile of each of the plurality of leakage ports comprises a discorectangular profile, the discorectangular profile comprising an elongated rectangular shape with semi-circular ends each having a diameter, and a leakage port of the plurality of leakage ports is separated from a neighboring leakage port of the plurality of leakage ports by a factor of the diameter of the semi-circular ends of the discorectangular profile.
A leakage component, comprising:
- a tubular first housing defining a first flow path between a first end portion and a second end portion;
- a ball joint surface adjacent to the second end portion and defined along an outer surface of the first housing;
- a plurality of leakage ports formed in the first housing and in fluid communication with the first flow path, wherein fluid flow through the plurality of leakage ports is configured to entrain ambient air into the fluid flow exiting the plurality of leakage ports to decelerate the fluid flow, a profile of each of the plurality of leakage ports comprises a discorectangular profile the discorectangular profile comprising an elongated rectangular shape with semi-circular ends each having a diameter, and a leakage port of the plurality of leakage ports is separated from a neighboring leakage port of the plurality of leakage ports by a factor of the diameter of the semi-circular ends of the discorectangular profile;
- a tubular second housing defining a second flow path, wherein the second housing is coupled to the first housing to permit fluid communication between the first flow path and the second flow path;
- and
- a socket surface defined within an inner surface of the second housing, wherein the socket surface is configured to movably couple with the ball joint surface.
A method to direct fluid flow, the method comprising:
- providing a tubular housing configured to accommodate a bulk expiration flow;
- diverting a portion of the bulk expiration flow to a plurality of leakage ports formed in the tubular housing, wherein a profile of each of the plurality of leakage ports comprises a discorectangular profile, the discorectangular profile comprising an elongated rectangular shape with semi-circular ends each having a diameter, and a leakage port of the plurality of leakage ports is separated from a neighboring leakage port of the plurality of leakage ports by a factor of the diameter of the semi-circular ends of the discorectangular profile;
- and
- entraining ambient air into the portion of the bulk expiration flow leaking through the plurality of leakage ports to reduce a velocity of the portion of the bulk expiration flow leaking through the plurality of leakage ports.
