Abstract
A diffusing corner for fluid flow within a wind tunnel comprising an arrangement of diffusing vanes for diverting the flow of air through the corner in a plurality of air passages having increasing cross-sectional area, thereby increasing the overall cross-sectional area of the wind tunnel and slowing the air flow. The vanes are configured to minimize turbulence and the loss of energy through the corner, and to attenuate transmission of sound generated within the wind tunnel.
Claims10
A diffusing corner for fluid flow within a fluid conduit, comprising a plurality of vanes arranged to divide the fluid conduit into a plurality of fluid passages, each of the plurality of vanes having a first surface and a second surface, the first and second surfaces being defined by non-circular sections, wherein the second surface of a first vane and the first surface of a second vane define one of the plurality of fluid passages, and wherein the plurality of vanes is arranged to direct the fluid flow through an angular displacement and an increase in cross-sectional area of the fluid conduit.
A vane within a fluid passage, the vane having inner and outer surfaces, each of the inner and outer surfaces being defined by non-circular sections and configured to divert a fluid flow through an angular displacement within the fluid passage, and adapted to be arranged with other like vanes within the fluid passage to increase the cross-sectional area of the fluid passage, thereby reducing the fluid velocity in a continuous fashion so as to minimize turbulent flow and energy loss due to turbulence.
