Abstract

The objective of this paper is to get an estimate of the Vertical Axis Turbine performance, through a theoretical- numerical approach which will help to validate later analysis and improvements of the turbine design. With the purpose to get a more realistic approach of the Vertical Axis Turbine theoretical performance, the variation of the mean drag coefficient (Cd) was determined using CFD (Computational Fluid Dynamics) considering the variation in a steady-state regime of the drag within different openings of the blades for different speeds
