The Fluid-Structure Interaction Analysis of the Inverted Umbrella Aerator Curved Blade

Abstract:

The blades are important components of the inverted umbrella aerators. In this paper, the inverted umbrella aerator blade with curved surface, which was arranged according to the variable helix angle of logarithmic spiral line, was designed and simulated. Through the simulation and calculation of the flow field of oxidation ditch that pushed by the blade, based on the fluid-structure interaction analysis, the reliability of the impeller blades has been studied. All the results showing that the new type inverted umbrella surface aerator blade is reliable.
