Fluid flow control device with different permeabilities
| DWPI Title: Fluid flow control device with graded permeability comprises insert body, which is shaped for sealing insertion into fluid flow structure for fluid flow, and has circular cross-section and first and second portion arranged concentrically such that second portion surrounds perimeter of first portion |
| Abstract: A fluid flow control device comprising an insert body having a first portion with a first permeability and second portion with a second permeability that is different from the first permeability. The insert body can be shaped for sealing insertion into a fluid flow structure for fluid flow therethrough. The first portion and the second portion can be arranged in the insert body to cause uniform fluid flow velocity of fluid in the fluid flow structure at an exit of the insert body when the fluid passes through the first portion and the second portion when the insert body is placed inside the fluid flow structure. |
| Use: Fluid flow control device with graded permeability. |
| Advantage: The fluid flow control device with regions having different permeability to control fluid flow velocities. |
| Novelty: Fluid flow control device comprises an insert body (102), which is shaped for sealing insertion into fluid flow structure for fluid flow. The insert body comprises first portion (104) with first permeability. The first portion is centrally located within insert body and second portion (106) with a second permeability. The second portion is located beyond distance from center of insert body such that the second portion is at farther distance from central axis of insert body as compared to the first portion. The first permeability of first portion is lower than second permeability of the second portion. The first portion and the second portion are arranged in insert body to cause fluid to pass through first portion and the second portion when the insert (100) body is placed inside fluid flow structure. The insert body has a circular cross-section and first portion and second portion are arranged concentrically such that second portion surrounds perimeter of the first portion. |
