The effect of the entrance hub geometry on the efficiency in an axial flow fan
International Journal of Refrigeration, 2019The improvement in efficiency of axial flow fans is major concern in turbomachinery industries including outdoor units of air conditioners. The end wall region is responsible for losses in axial flow fan.

Numerical and experimental study of a reversible axial flow fan
International Journal of Computational Fluid Dynamics, 2020Reversible axial flow fans, used in tunnel ventilation systems are designed in a way that as the direction of impeller rotation changes, suction and discharge directions change without any sensible change in flow rate and pressure.

Effect of a casing fence on the tip-leakage flow of an axial flow fan
International Journal of Heat and Fluid Flow, 2019The effect of a casing fence on the tip-leakage flow of an axial flow fan is investigated using large eddy simulation. A fence is attached on the shroud near the trailing edge of an axial flow fan used in an outdoor unit of air conditioner.

Design of an Axial Flow Fan for a Unique Cooling Application
Volume 5: Education; Electric Power; Fans and Blowers, 2022A rotor-only axial flow fan is designed for use in a concentrated solar power application. The plant uses a supercritical carbon dioxide Brayton Cycle for power generation and an air-cooled heat exchanger (ACHE) for cooling.

Effect of porous casing on small axial-flow fan noise
, 2021A novel casing treatment is studied to suppress the tip leakage vortex and postpone stall inception, leading to significant noise reduction. The new casing is made by open-cell metal foam, and its effect on both aerodynamic and acoustic performance of an

Investigation of Flapping Wings as an Alternative to Axial Flow Fans
AIAA SCITECH 2022 Forum, 2022© 2022 by MBDA UK Ltd. Published by the American Institute of Aeronautics and Astronautics, Inc., with permission.Flapping wings appear to be an innovative approach as an alternative to axial flow fans. In this study, the flapping motion has been defined as a linear combination of pitching and plunging.
