Multi-Objective Optimization for the Radial Bending and Twisting Law of Axial Fan Blades
Processes, 2022 The performance of low-pressure axial flow fans is directly affected by the three-dimensional bending and twisting of the blades. A new blade design method is adopted in this work, where the radial distribution of blade angle and blade bending angle is ...

Energy Efficiency Optimization Design of a Forward-Swept Axial Flow Fan for Heat Pump
Frontiers in Energy Research, 2021 As one of the key components of the heat pump system, compared to that of a conventional axial fan, the blade tip area of a forward-swept axial fan is much larger than its blade root, which is the main noise source of the fan and also has an important ...
