METHOD AND SYSTEM FOR A SHORT LENGTH JET PUMP WITH IMPROVED MIXING

摘要

A method and system for a jet pump is provided. The jet pump system includes a pre-mixing bowl includes a nozzle, a mixing section at least partially surrounding the nozzle, and a first inlet opening configured to receive a first flow of fluid and direct the first flow of fluid to an inlet of the nozzle. The pre-mixing bowl further includes a second inlet opening configured to receive a second flow of fluid and to direct the second flow of fluid to the mixing section. The second inlet opening includes a first inlet opening area. The second inlet opening includes an entry angle into the pre-mixing bowl that is oblique with respect to the central axis. The pre-mixing bowl further includes a third inlet opening configured to receive a third flow of fluid to direct the third flow of fluid to the mixing section.

1. A jet pump system comprising:
a pre-mixing bowl comprising: a nozzle comprising a central axis; a mixing section at least partially surrounding said nozzle; a first inlet opening configured to receive a first flow of fluid from a first pressurized fluid source and direct the first flow of fluid to an inlet of said nozzle; and a second inlet opening configured to receive a second flow of fluid from a second pressurized fluid source and to direct the second flow of fluid to said mixing section, said second inlet opening comprising a first inlet opening area, said second inlet opening comprising an entry angle into said pre-mixing bowl that is oblique with respect to the central axis; a third inlet opening configured to receive a third flow of fluid from the second pressurized fluid source and to direct the third flow of fluid to said mixing section, said third inlet opening comprising a second inlet opening area, said third inlet opening comprising an entry angle into said pre-mixing bowl that is oblique with respect to the central axis; and an outlet opening configured to direct the first, second and third flows of fluid from said pre-mixing bowl; and a mixing tube extending from said outlet opening aligned with the central axis.
