Wind Fisher called upon the Computational Fluid Dynamics office at Extia to perform numerical aerodynamics studies for Magnus effect kites. We are extremely happy collaborating with Valentin Rat and Steven Daix who evaluated and provided further insight into the fluid flow around spinning cylinders as published by Badalamenti. They went above and beyond the call of duty to give confidence in the aerodynamic coefficients which lead to our unique performance capabilities to efficiently harness wind energy. We definitely recommend their work and won’t hesitate to ask for their help to support our start-up.
