Vortex Control Using Plate Type Floor Splitter in Pump Intake

Pump sump design is very crucial in ensuring a minimum requirement for its operation. Improper pump will influence the development of vortices and swirls that can adversely affect efficiency which subsequently could damage pump. This be mitigated by installing an anti-vortex device (AVD) beneath intake pipe sump. The AVD works suppressing flow water into pipe. ANSI/HI 9.8-2012 standard has outlined various shapes concepts used. experimental study was conducted to determine appropriate parameters configurations twin plate floor splitter (TPFS) suppress vortex Geometries other outlines experiments were based on guidelines 9.8-2012. model variations used models with no splitter, single (SPFS), TPFS 25 mm, 45 mm 65 gap variations. results showed distance between two sides affects number generation swirl angle reduction. increased plates but lower localized intensity. However, produced less than 5° variation producing lowest 2.41°. use shows significantly improved performance reduction suppression as compared case.
