  • Patent number: 9745998
    Abstract: A centrifugal air blower includes a casing having a spiral scroll, an impeller contained in the casing, an inlet side panel having an inlet, and a motor-fixing side panel fixing a motor. The centrifugal air blower further includes a first triangle wall and a second triangle wall at a discharge outlet opposite to a tongue. The triangle wall where air velocity inside the casing is slower is shaped with a longer vector component (length B) in the direction from the discharge outlet to the impeller than the other triangle wall. This configuration makes the air velocity near the discharge outlet uniform and suppresses a decrease of static pressure, an increase of power consumption, and turbulent flow noise.

  • Patent number: 8821117
    Abstract: A fluid turbine apparatus which is able to increase the fluid velocity and consequently increase the rotation speed of the fluid turbine. The fluid turbine apparatus has a convergent section, a fluid turbine section and a divergent section. The fluid enters into the fluid turbine through the convergent section, passes through the fluid turbine and exits through the divergent section. The combination of the convergent section and the divergent section creates a Venturi effect and increases the fluid velocity and thus the energy density entering turbine for increasing the energy extracted by the turbine.

  • Patent number: 8813689
    Abstract: A centrifugal fan with a pot-like impeller and with a housing, having a first circumferential wall region with an arc-like curvature which extends directly along the impeller. The housing includes in a direction of rotation of the impeller a second circumferential region with a radial distance from the impeller increasing spirally up to an outlet region. The housing includes in an opposite direction a third circumferential wall region extending to the outlet region, having an S-curvature and including a sub-region curved in the same direction as the first circumferential wall region forming a flow baffle element. Two side walls cover the axial end faces of the impeller wherein one of the side walls extends into the pot-like impeller and divides its interior into a first suction chamber having an intake and a second suction chamber. The outlet region expands in cross-section in the outlet flow direction.

  • Patent number: 8807930
    Abstract: An airfoil comprises pressure and suction surfaces extending axially from a leading edge to a trailing edge and radially from a root section to a tip section, defining a mean span therebetween. An inner endwall defines an inner endwall contour extending axially and circumferentially from the root section, and an outer endwall defines an outer endwall contour extending axially and circumferentially from the tip section. The inner and outer endwall contours are defined by varying radial deviations from circumferentially uniform nominal inner and outer radii, where one of the radial deviations varies axially and circumferentially by at least three percent of a mean span of the airfoil.
