NUMERICAL INVESTIGATION OF MODIFIED SAVONIUS WIND TURBINE WITH VARIOUS STRAIGHT BLADE ANGLE
Journal Title: Journal of Mechanical Engineering Research & Developments (JMERD) - Year 2018, Vol 41, Issue 3
Abstract
The present paper aims to numerically investigate the two-dimensional flow analysis of modified Savonius wind turbine using computational fluid dynamics. The effects of the straight blade angle on the turbine performance were studied. Simulations based on the RANS equations and the SST-k- turbulence model are used to simulate the airflow over the turbine blades. Both the static and dynamic simulations were performed. In the static simulation, the drag and lift coefficient on the Savonius turbine were directly calculated at every angular position, and the time-averaged moment and power coefficients were computed in each of the dynamic simulations. From the results, it can be concluded that the turbine with a straight blade angle of 100 model gives the better performance at higher Tip Sped Ratio (TSR) than other models.
