摘要： An apparatus for reducing heating effects of an exhaust plume of a jet engine on an impinged surface includes fluid injectors disposed adjacent and aimed into an exhaust plume zone that's to be occupied by an exhaust plume when the engine is running. A flow generator transmits fluid flow into such an exhaust plume through the injectors. Each injector emits fluid in at least two divergent directions to increase the cross-sectional area of the exhaust plume by forming fluidic lobes in the exhaust plume.
摘要翻译： 用于减少喷射发动机在冲击表面上的排气羽流的加热效应的装置包括与发动机运行时被排气羽流占据的排气羽流区相邻并且被瞄准的流体喷射器。 流动发生器通过喷射器将流体流传递到这样的排气羽流中。 每个喷射器以至少两个发散方向发射流体，以通过在排气羽流中形成流体波瓣来增加排气羽流的横截面面积。

摘要： An exhaust impingement cooling device for reducing heating effects of an exhaust plume on an impinged surface. An exhaust nozzle exit screen is positioned across an exhaust plume flow path, and includes a plurality of flowpath diverging apertures that spread at least a portion of an exhaust plume that is being emitted along the exhaust plume flow path from an exhaust plume source. Flow control jets are arrayed within the exhaust plume flow path in respective positions where their operation will augment the flow of exhaust plume gases through the screen, thereby increasing the momentum and mixing of the exhaust plume with cooler ambient air.

摘要： A tapered micro-plow, or a series of tapered micro-plows, are submerged in a boundary layer just upstream of a reflection point of an oblique shock. Each micro-plow develops a beneficial pair of vortices which redistribute high energy flow within the boundary layer such that flow separation is prevented or delayed. The beneficial vortex pairs rotate about an axis that is parallel to the flow of fluid, and together rotate such that they induce a velocity on one another which tends to hold them near the surface and delay vortex lift-off.
摘要翻译： 锥形微犁或一系列锥形微犁淹没在刚刚在倾斜冲击的反射点上游的边界层中。 每个微型犁形成一对有益的涡流，其在边界层内重新分配高能量流，从而防止或延迟流动分离。 有益的涡流对围绕平行于流体流动的轴线旋转，并且一起旋转，使得它们彼此相互感应，倾向于将它们保持在表面附近并延迟涡流剥离。
