Abstract: In order to solve the current problems of low power conversion efficiency of aerators and uneven fluid velocity in various parts of aerators, the linear and kinematic parameters of airfoil aerator blades are the main research content, and a new type of blade with non-equal variation angle as logarithmic helix and NACA0012 airfoil type as profile is designed for application in airfoil aerators. Through theoretical and numerical analysis of the airfoil performance, design of the new airfoil using 3D modelling, and numerical simulation of the new airfoil and analysis of the post-simulation data, the aerodynamic characteristics and turbulent energy of the new aerator blade for the airfoil aerator are investigated in depth.
