Description:
The simulation and description of the fluid mechanics is made from several dynamic models of approach depending on the variables and the phenomenon to consider, when the viscous effects are not considerable, these can be simulated and studied from the potential flow theory. Here this theory is used to describe how the Magnus effect happens, through the superposition of several potential flows and calculating the lift forces that act on a cylinder with circulation embedded in a fluid. As these are considered non viscous effects, the calculations for the drag force gives zero causing the well-known D'Alembert's paradox. The paper builds a model using potential theory to calculate its expression and then exposed as it relates to the development of vorticity for a body with movement and without movement.
