Performance Optimization of Small Centrifugal Fans Based on ANSYS
Small centrifugal fans are the core components in quick-freezing refrigeration equipment. They operate through a process where an electric motor drives the impeller to rotate, converting mechanical energy into potential energy. This paper first calculates the range of blade quantities using theoretical formulas for blade number selection, then simulates the working state of small centrifugal fans using ANSYS Workbench. Finally, it compares and analyzes parameters such as pressure, flow rate, torque, and efficiency of centrifugal fans with different numbers of blades. By first calculating the range of centrifugal impeller quantities through theoretical methods and then combining it with Fluent simulation analysis, this paper obtains the optimal number of blades in a more scientific and reasonable manner.
