A single-stage axial fan having a pressure ratio of 1.01 is designed in the current study. The design chosen based on power available from existing motor (2.2 kW). space for flow was generated by varying specific and geometrical parameters suitable steps, using program written MATLAB. varied are mass rate, inlet Mach number, angle, rotor speed. that were hub to tip ratio, aspect blade solidity....

To improve the performance of aerodynamic properties and reduce noise an axial flow fan in outdoor unit air conditioner, this study proposed a bionic forked trailing-edge structure inspired by fish caudal fin implemented modifying trailing edge prototype fan. The effect on aeroacoustic was investigated experimentally, detailed analyses blade load internal vortex structures were performed based ...
