Current Protocols in Protein Science, 1995
AbstractThis appendix provides rmax values (the maximum value of the rotating radius between the particle being centrifuged and the axis of rotation) for commonly used rotors manufactured by Du Pont (Sorvall), Beckman, Fisher, and IEC. Additionally, nomograms are provided for determining the relative centrifugal force (RCF) where speed and rmax are ...

Aerodynamic and acoustic investigations of rotor-rotor wake interaction
Proceedings of the International Symposium on the Application of Laser and Imaging Techniques to Fluid MechanicsThe paper presents part of the experimental activities carried out in the GARTEUR Action Group RC/AG-26 to study the acoustic and aerodynamic characteristics of small rotor configurations, including the influence of the rotor-rotor interactions. Two rotors, equipped with two-bladed propellers of a diameter of D=330.2 mm, were operated at two rotating ...

Wind turbine rotor aerodynamics
2017Wind turbines are operating under very complex and uncontrolled environmental conditions, including atmospheric turbulence, atmospheric boundary layer effects, directional and spatial variations in wind shear, etc. Over the past decades, the size of a commercial wind turbine has increased considerably.
