Effect of Axial Sweep and Tip Extension on Performance of an Axial Fan
Volume 1: Advances in Aerospace Technology, 2016Performance enhancement in terms of stall margin increment, increased pressure rise coefficient and increased efficiency is of great need for low speed axial fans. Stacking line modifications in terms of sweep, skew, dihedral or combination of these, as well as blade tip geometry modifications are assumed to be one of the ways to achieve finite ...

Unsteady Pressure Measurement of an Axial Fan
Fluids Engineering, 2001Abstract An unsteady pressure measurement system was developed to measure the unsteady pressure field of an axial fan. The fan unsteady pressure fields of an inlet and outlet were obtained at three axial positions for seven-radial directions. The results showed that there is a relatively long response time for pressure drop both in inlet

Flow reversal in axial fans is usually performed by the change of revolution direction and by stator vanes turning. Derived relations express the relative position of characteristics curves for reverse and normal flows. The ratio of volume flow rates at these conditions decreases with rotor blade profiles camber (aerodynamic loading) and with flow ...

Design of a Flux-Switching PM Machine with Axial Fan Capability
2018 IEEE International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles & International Transportation Electrification Conference (ESARS-ITEC), 2018The objective of this paper is to design and investigate a flux-switching PM machine which has the capability of both motoring and axial fan function. The rotor poles are shaped like fan blades to provide the function of axial fans.

Constant acoustic fan curves for 92 mm axial fans.
The Journal of the Acoustical Society of America, 2010The noise emission of fans changes as a function of the operating point. Airflow and acoustic fan plenum experiments can be used to characterize these effects to estimate noise under installed conditions. Recently, the concept of iso-acoustic fan curves was introduced by various authors, and results were presented for small radial blowers and some ...

Flow characteristics of axial fan with shroud
Journal of Fluid Machinery, 2008Axial fan without static blades requires the duct as a guidance for unskewed inflows. This work examined the geometric effects of a duct guided the in and out flows through an impeller. The present methodologies are computational predictions with parallel work by experimental validation. Several different positions of a rotor in a duct are proposed for
