Abstract: The disclosed finger seals are designed to be operational under rotational velocity or a stationary condition. The contact surface of the finger seals is inclined in an axial direction. This incline causes a convergent leakage path between the finger foot surface and the bore. Therefore, the leakage flow passing through this gap exerts hydrodynamic lift on the finger and lifts the finger from the bore surface at design pressure. Since the slope is in the axial direction, the rotational velocity of the bore does not affect the hydrodynamic lift and the finger seals can operate at any rotational speed, unlike prior finger seal where the hydrodynamic lift is generated by rotational velocity. Each finger seal is pressure balanced. The pressure chambers on the two sides of each finger seal are connected through the finger cutouts. The finger seal design is such that the fingers lift and move away from the bore surface in radial direction. Therefore, the angle between the finger seal foot and the bore is constant at any lifted distance. In each seal stack up, in one form, each finger seal is designed with the specific required length to allow sufficient surface area for the hydrodynamic force such that the finger seals would be lifted from the bore surface at the design pressure.
Abstract translation: 所公开的指状密封件设计成在旋转速度或静止状态下可操作。 手指密封件的接触表面沿轴向倾斜。 这种倾斜导致手指脚表面和孔之间的会聚泄漏路径。 因此，通过该间隙的泄漏流在手指上施加流体动力升力，并在设计压力下从手指表面提起手指。 由于斜面在轴向方向上，孔的旋转速度不影响流体动力升力，并且手指密封可以以任何旋转速度操作，这与先前的手指密封不同，其中流体动力升力由旋转速度产生。 每个手指密封是压力平衡的。 每个手指密封件两侧的压力室通过手指切口连接。 手指密封设计使得手指在径向方向上抬起并远离孔表面移动。 因此，手指密封脚和孔之间的角度在任何提升距离处是恒定的。 在每个密封堆叠中，以一种形式，每个指状密封件被设计成具有特定的所需长度，以允许足够的流体力学表面积，使得手指密封件将在设计压力下从孔表面提升。

Abstract: Provided herein are multiple variations, applications, and variations for producing electrical power from a flowing fluid such as a gas or liquid under pressure, for example natural gas flowing through a pipeline, by means of one or more positive displacement devices that drive one or more electrical generators. The electrical generators may be immersed in the flow stream together with the positive displacement devices as disclosed, or alternately may be isolated from the flow stream, such as by magnetic coupling, in order to promote longevity and to decrease the risk of accidental discharge or explosion of the fluid in the flow stream. To further decrease such risks, the positive displacement devices may isolate the drive fluid from the environment without the use of dynamic seals.

Abstract: Disclosed herein is a valveless multitube pulse detonation engine including: a plurality of detonation tubes, wherein each detonation tube comprises an independent discharge outlet, and the plurality of detonation tubes interconnected at a common air/fuel mixture intake port. In the disclosed engine, an air and fuel mixture is detonated in the detonation tubes simultaneously, and the common air/fuel mixture intake port minimizes back-pressure caused by detonating the air/fuel mixture by directing multiple reverse shock waves into one another and effectively using the back-pressures as reacting surfaces for one another and effectively reducing the effect of back flowing shock waves moving towards upstream. The detonation tubes may be non-linear, and may have independent discharges. The independent discharges may be coupled to an adapter nozzle terminating in a combined exhaust outlet.

Abstract: This disclosure concerns an advanced nutating positive displacement device having a high power to mass ratio and low production cost. This device in one example forms an exemplary pump as will be discussed in detail. The examples disclosed herein are of the rotary positive displacement type, but in a class by themselves. The devices are formed by a nutating rotor having a face comprising lobes and valleys, and a fixed stator also having a face with lobes and valleys. The face of the rotor opposes and cooperates with the face of the stator. The opposing faces define chambers that change volume with rotation of the rotor.

Abstract: A pressure gain combustor comprises a detonation chamber, a pre-combustion chamber, an oxidant swirl generator, an expansion-deflection (E-D) nozzle, and an ignition source. The detonation chamber has an upstream intake end and a downstream discharge end, and is configured to allow a supersonic combustion event to propagate therethrough. The pre-combustion chamber has a downstream end in fluid communication with the detonation chamber intake end, an upstream end in communication with a fuel delivery pathway, and a circumferential perimeter between the upstream and downstream ends with an annular opening in communication with an annular oxidant delivery pathway. The oxidant swirl generator is located in the oxidant delivery pathway and comprises vanes configured to cause oxidant flowing past the vanes to flow tangentially into the pre-combustion chamber thereby creating a high swirl velocity zone around the annular opening and a low swirl velocity zone in a central portion of the pre-combustion chamber. The E-D nozzle is positioned in between the pre-combustion chamber and detonation chamber and provides a diffusive fluid pathway therebetween. The ignition source is in communication with the low swirl velocity zone of the pre-combustion chamber. This configuration is expected to provide a combustor with a relatively low total run- up DDT distance and time, thereby enabling high operating frequencies and corresponding high combustor performance.
