FLUID MACHINE IN WHICH FLOW STABILIZER IS FITTED IN TUNNEL SHAPE IN COAXIAL GROOVE AND EDGE AND AT END OF BLADE OF FLUID MACHINE IN CONSIDERATION OF HEIGHT, WIDTH, AND RESISTANCE SINCE BLADE OF FLUID MACHINE MAKES PARALLEL FLOW AREA AND PROVIDES ENTRAINED FLOW ON OUTER PERIPHERY AND WHICH IS SUBJECT TO TOTAL WEDGE TREATMENT

摘要

<P>PROBLEM TO BE SOLVED: To provide a blade for reducing resistance by a total wedge treatment by providing a coaxial groove and an edge to the blade, identifying flow areas, and fitting a flow stabilizer in a tunnel shape into the outermost periphery of the blade as a result of the analysis of the flow of a fluid and the changes of volume and density under the conditions in which the blade of the fluid machine does not have a mechanism for axially moving the fluid, the absence of the mechanism generates a centrifugal force, and a defect such as cavitation is left unrepaired. Ž<P>SOLUTION: This fluid machine is adaptable to both an improvement measure in which a conventional processing method is used and a method in which the entire blade is made by assembling novel plate parts. In any case, the measure against cavitation is taken by providing the mechanism for causing an axial flow to the blade. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
