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

Behavior of the Blade Tip Vortices of a Wind Turbine Equipped with a Brimmed-Diffuser Shroud
Energies, 2012 To clarify the behavior of the blade tip vortices of a wind turbine equipped with a brimmed-diffuser shroud, called a “Wind-Lens turbine”, we conducted a three-dimensional numerical simulation using a large eddy simulation (LES ...

Numerical Study On Parametrical Design Of Long Shrouded Contra-Rotating Propulsion System In Hovering [PDF]
, 2011 The parametrical study of Shrouded Contra-rotating Rotor was done in this paper based on 2D axisymmetric simulations. The calculations were made with an actuator disk as double rotor model. It objects to explore and quantify the effects of different shroud geometry parameters mainly using the performance of power loading (PL), which could evaluate the ...

Comparison of a Miniaturized Implantable Two-Stage Rotodynamic Blood Pump to Equivalent Single-Stage Concepts. [PDF]
Artif OrgansThis study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

Engineering 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
