ABSTRACT:
This invention relates to a method and apparatus for producing fluid pressure from mechanical energy. The apparatus is of the turbomachine type and includes blowers, compressors, pumps, turbines, fluid motors, and the like. This invention also relates to a method of generating pressurized fluid in which the flow of fluid is first deflected by a substantial amount while simultaneously maintaining the relative velocity following said deflection approximately equal to the relative velocity prior to said deflection fluid at least at one location between hub and tip followed by generating pressure by turning back the flow of fluid by an amount approximately equal to the amount of deflection of the fluid while simultaneously decelerating the flow of fluid and keeping the ratio of the axial through flow velocity through the fluid flow path to the outlet velocity following the generation of said deflection equal to approximately 0.66 or less. The invention also relates to a method and apparatus for controlling a boundary layer along flow directing surfaces contained within a blower, pump and the like. The invention also relates to the method and apparatus for producing fluid pressure from mechanical energy while simultaneously controlling the boundary layer formed on the flow directing surfaces contained in the fluid flow path.
