Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To control the turbulence of a flow in a fluid inflow part by converting the fluid flow along a column side by 90 deg. by the column and a flow guide contacting therewith. SOLUTION: The exposition of the shape of a bell-bottom and non-hollow axial-symmetry flow guide 31 to the outside as the bell-bottom shape of axial symmetry can miniaturize α1 and α2 in the top face and the bottom face so as to make them acuter than those designed by matching the 'external appearance' with each other. A plurality of bell-bottom flow guides 33 with less turbulence flow as fluid separators are arranged at some intervals apart from the flow guide 31 surface converting the flow along the side of the column 32 by 90 deg. by the column 32 and the flow guide 31 contacting therewith. Adoption of a design idea setting the guide to an aeromechanically smooth shape can remove the turbulence factor generated in the upstream side of the flow or the defect of the spontaneous circulating flow generator.
