This work analyzes the performance of two vertical-axis hydrokinetic
turbines - a conventional Savonius rotor (TS) and an alternative flat-bladed
turbine (TA) - through two-dimensional computational fluid dynamics simulations. Both geometries were evaluated under equivalent Reynolds numbers,
allowing a direct comparison of their aerodynamic behavior. The methodology
involved locally refined meshes, transient URANS simulations using the SST
k-w turbulence model, and a tip speed ratio sweep from 0.3 to 1.3. The simulations were validated against experimental wind-tunnel data available in the
literature by modeling a traditional Savonius rotor. After this validation step,
the alternative turbine was simulated and its performance compared with laboratory measurements from LEF/PUC-Rio. Results showed good agreement
between numerical and experimental curves for the Savonius rotor, while the
alternative turbine exhibited greater geometric sensitivity and larger discrepancies at low T SR. Overall, the Savonius turbine outperformed the alternative
design within the simulated operating range.
