  • Patent number: 10100846
    Abstract: A fan design method and fan structure is described, enabling independent control of the volume of airflow and the amount of noise produced. The noise produced is a close approximation to a pleasing red noise spectrum, and is generated solely by the interaction of the rotating fan blades with a petal assembly or a fan enclosure in several embodiments. A petal assembly may be positioned at varying spacings behind the rotating fan blades to control the level of noise production with minimal effect on the volume of airflow. Various aspects of the fan blade configuration, such as the blade pitch, camber, span, chord, etc., may be manipulated to control the ratio of airflow volume to the amount of noise produced.

  • Patent number: 10024330
    Abstract: A bladeless cooling light includes an airflow assembly, a light assembly, and a housing. The airflow assembly includes an air circulation assembly positioned within the housing and an air passage structure connected to the housing, wherein the air circulation assembly draws air through the housing into the air passage structure. The air passage structure has a separation wall that delineates the air passage structure into an inflow air channel and an outflow air channel to improve the airflow through the air passage structure. A cone-tip hole grid and a wired heater within the air passage structure further improve airflow characteristics; the cone-tip hole grid constricts the flow, while the wired heater increases internal pressure by heating the air. The lighting assembly is mounted to the housing with the air passage structure being positioned around the lighting assembly, such that the light and expelled airflow are projected in the same direction.

  • Patent number: 10006309
    Abstract: An exhaust diffuser for a gas turbine includes an annular duct. A row of struts is arranged in the duct. In a region downstream of the trailing edges of the struts, the cross-sectional area of the duct decreases to a local minimum and then increases again towards the outlet end of the duct. Thereby the gas flow is locally accelerated downstream of the struts. This stabilizes the boundary layer of the flow in this region and leads to a marked increase in pressure recovery for a wide range of operating conditions.
