The paper presents a historical overview of the developments of aerodynamic design
methods for low-speed axial-flow fans. This historical overview starts from the first fan …

The sound generated by axial flow fans has become increasingly important in several
industrial areas. These devices represent considerable noise sources that must be …

SUMMARY A rig has been designed and constructed according to the ISO 5801 Standard,
to test fans with a maximum inlet diameter equal to 0.8 m. The rig design procedure, that …

This paper presents a simple but complete design method to obtain arbitrary vortex design
tube-axial fans starting from fixed size and rotational speed. The method couples the …

This paper tries to link the research that has been conducted in the field of design and
optimisation of axial fans. The attempts are made towards blade design, effects of sweep, tip …

The authors previously suggested a simple method to design forward-swept axial-flow rotors
with blades having low hub-to-tip and high aspect ratios. This design method was …
