Abstract:
1. 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.
