Improved Aerodynamics of a Hollow-Blade Axial Flow Fan by Controlling the Leakage Flow Rate by Air Injection at the Rotating Shroud [PDF]

open access: yesEntropy, 2021
Axial flow fans are used in many fields in order to ensure the mass and heat transfer from air, chiefly in the heating, ventilation and air conditioning industry (HVAC). A more proper understanding of the airflow behavior through the systems is necessary

CFD STUDY OF THE LEAKAGE FLOW IN LOW-SPEED AXIAL-FAN WITH ROTATING SHROUD

open access: yesProceedings of ... European Conference on Turbomachinery Fluid Dynamics & Thermodynamics, 2023
The paper reports a study of the effect of the rotational speed on the leakage flow development in a low-speed shrouded axial fan. As the rotor deforms due to centrifugal force and aerodynamic loading, a static structural analysis has been operated at five rotational speeds ranging from 500 to 3000 rev/min, with the pressure distributions on the rotor ...

Effect of impeller inlet diameter on saddle-shaped positive slope and non-uniform flow patterns at low flow rates of a mixed-flow pump

open access: yesEngineering Applications of Computational Fluid Mechanics, 2022
Most mixed-flow pumps obtain a saddle-like Q-P curve with a backflow, owing to the increased incidence angle at low flow rates. The backflow was developed near the shroud and followed downstream again at its end to form a recirculating flow. The rotating

Measurement Of Aerodynamically Induced Blade Distortion On A Shrouded Counter-Rotating Prop-Fan [PDF]

open access: yesProceedings of the International Symposium on the Application of Laser and Imaging Techniques to Fluid Mechanics, 2022
Blade deformation on a 1 m diameter composite fan rotor is measured simultaneously using stereoscopic image pattern correlation technique (IPCT) and blade-tip imaging. Absolute referencing of the blades is made possible by simultaneously tracking a marker on the hub using a fourth camera.
