摘要： A trapped vortex combustor for gas turbine engines. An annular combustor housing is provided having a plurality of inlet centerbodies disposed along a helical axis. The inlet centerbodies include a leading edge structure, opposing sidewalls, a pressurizable cavity, and a rear wall. Inlet centerbodies cooperate with adjacent structure and an aft bluff body to define a trapped vortex cavity combustion chamber for mixing an inlet fluid and burning fuel to form hot combustion gases. Mixing is enhanced by utilizing struts adjacent to the rear wall to create eddies in the fluid flow, and by injecting fuel and/or air in opposition to swirl created by the bulk fluid flow. Hot combustion gases are utilized in a turbine for extraction of kinetic energy, or in heat exchange equipment for recovery of thermal energy. High combustion efficiencies and less than 10 ppm emissions of oxides of nitrogen and of carbon monoxide are achieved.

摘要： A process for treatment of water via membrane separation equipment (Fig.2). A feedwater (10) is maintained or adjusted to a pH of 4.3 or lower, and fed to a membrane separation system. In this manner, species such as TOC become more ionized, and (a) their rejection by the membrane separation process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Passage of TOC through the membrane is significantly reduced. A recovery ratio of eighty percent (80%) or higher is achievable with most feedwaters, while simultaneously achieving a substantial reductio in cleaning frequency of the membrane separation equipment. The method is particularly useful for the preparation of high purity water (54).

摘要： Metal cold-working tooling (90) and method of employing such tooling. The tooling is used to produce deformation in a workpiece (132), to provide a selected beneficial residual stress profile in the workpiece, in order to provide high fatigue life structures in a minimum number of manufacturing steps. An indenter (90) is used to coldwork a workpiece, causing dimples (170) in the workpiece (132). Preferably, the dimples are provided with a shape formed by application of a uniform pressure profile to the workpiece surface. As optimized, a relatively uniform beneficial residual stress profile is provided at both the surface and at the midplane apertures in a workpiece, so as to improve overall fatigue life. Also, an improved indenter tool profile shape is described, having a smoothly curved indenter surface portion (92). And, the use of consumable lamina wafers (W(1), W(2)) provides the benefit of easy application of uniform stress profile to a workpiece.

摘要： A trapped vortex combustor. The trapped vortex combustor is configured for receiving a lean premixed gaseous fuel and oxidant stream at a velocity which significantly exceeds combustion flame speed in a selected lean premixed fuel and oxidant mixture, thus allowing use of high hydrogen content fuels. The combustor is configured to operate at relatively high bulk fluid velocities while maintaining stable combustion and low NOx emissions. The combustor is useful in gas turbines in a process of burning synfuels, as it offers the opportunity to avoid use of diluent gas to reduce combustion temperatures. The combustor also offers the possibility of avoiding the use of selected catalytic reaction units for removal of oxides of nitrogen from combustion gases exiting a gas turbine.
摘要翻译：被捕获的涡流燃烧器。被捕获的涡流燃烧器被配置成以选择的稀混合燃料和氧化剂混合物中显着超过燃烧火焰速度的速度接收贫预混气态燃料和氧化剂流，从而允许使用高含氢燃料。燃烧器被配置为在保持稳定燃烧和低NOx排放的同时以相当高的散装流体速度运行。燃烧器在燃烧同步燃料的过程中可用于燃气轮机，因为它提供了避免使用稀释气体来降低燃烧温度的机会。燃烧器还提供了避免使用选定的催化反应单元从燃气轮机的燃烧气体中除去氮氧化物的可能性。

摘要： A method for cold working spot welded structures to improve fatigue life, and structures made by the method. Partially finished structures are provided assembled and joined by a spot weld nugget. Opposing indenters, or an indenter and a backing anvil, are used to squeeze the spot weld nugget to form one or two cold working dimples, respectively. Residual compressive stress is imparted in the workpiece, resulting in increased fatigue life.

摘要： Rivetless nutplates, and method of installing fastening elements. Rivetless nutplate fasteners are installed in structures, and particularly metal structures, by providing flush fit barrel shaped plug or bushing portions in a hole in the structure as defined by an edge wall. The barrel portion is acted upon axially, and expanded radially outward toward the edge wall of the hole, to provide an interference fit. The ends of the barrel portion are machined as desired for flushness. Also, a hole is installed as necessary. Rivetless nutplates are easily installed, and the installation enhances fatigue life of the hole surrounding the barrel of the nutplate.
