Abstract
The purpose of this work is to investigate the flow around plain and ribbed rotating cylinders based on Magnus Effect. Some features are parameterized such as the free flow velocity, the cylinder angular velocity and the wall average roughness. CFD study with Comsol Multiphysics® is carried out to approximate solutions to the velocity field and the drag and lift coefficients. A validation and independency mesh analysis are proceeded. It is important to mention that this kind of study has its application on wind mills with cylindrical-bladed turbines for low wind velocities. It is found that increasing the angular velocity of the cylinders augments lift forces. Complex surface structures such as roughness, and grooves may strongly affect forces on the blade surface.
