Abstract
A system for an engine is provided herein. The system includes a primary passage, a suction passage, and an outer casing coupling the primary and suction passages such that a primary axis is orthogonal to a suction axis. The system further includes a jet pump assembly coupled to the primary passage forming an annular channel between the outer casing and the jet pump assembly. Further, the jet pump assembly includes a flow divider positioned opposite from the suction passage within the annular channel.
Claims12
A system for an engine, comprising:
- a primary passage;
- a suction passage;
- an outer casing coupling the primary and suction passages such that a primary axis is substantially orthogonal to a suction axis;
- and
- a jet pump assembly coupled to the primary passage forming an annular channel between the outer casing and the jet pump assembly, the jet pump assembly including a flow divider positioned opposite from the suction passage within the annular channel;
- and
- a nozzle coupled to the flow divider and fluidically coupled to the primary passage, the nozzle positioned between the flow divider and the suction passage along the suction axis, the nozzle including one or more constricting regions that constrict a flow of a fluid through the nozzle, the nozzle further including a hollow cylinder portion and a hollow conical frustum portion, wherein the outer casing follows a contour of the hollow cylinder portion and the hollow conical frustum portion, while maintaining the annular channel;
- and further
- wherein the flow divider includes a first portion and a second portion, the first portion coinciding with the hollow cylinder portion and the second portion coinciding with the hollow conical frustum portion.

A jet pump assembly, comprising:
- a nozzle including a constricting portion and a cylindrical portion;
- an outer casing housing the nozzle to form an annular channel therebetween;
- and
- a flow divider including a first surface that follows a contour of the constricting portion, a second surface that follows a contour of the cylindrical portion, a transition point that connects the first and second surfaces, and two fluid contact surfaces orthogonal to the constricting portion and the cylindrical portion.
