Benchmarking table for recent researches on the Savonius turbine.
| References | Blades type | Method and analysis | Key findings |
|---|---|---|---|
| This work | Partially deformable blades | Numerical analysis (CFD) | A remarkable improvement in torque coefficient with 32%. |
| Dominicus et al. [17] | Slotted Blades | Experimental investigation | The turbine with a 10% overlap ratio showed the best performance with an improvement of 28% in power coefficient. |
| Fatahian et al. [18] | Blades with deflector | Numerical analysis (CFD) | By adding a deflector, the power coefficient enhanced dramatically up to 24.2%. |
| Kaya et al. [19] | Elliptical blades | Numerical analysis (CFD) | The elliptical design model produced a maximum power coefficient that was over 30 greater than the based one. |
| Priyadumkol et al. [20] | Modified Blade | Experimental investigation | A higher power coefficient compared to the conventional rotor by 6.67% and 18.75% for a Reynolds number of 136640 and 156160, respectively. |
| Manganhar et al. [21] | Blades with Guiding rotor house | Numerical analysis (CFD) | The implementation of GRH led to an enhancement in the rotor’s power coefficient of roughly 27% |
