Performance investigation of an innovative vertical axis turbine consisting of deflectable blades

A review on technology, configurations, and performance of cross‐flow hydrokinetic turbines

“…Rotors for drag force based configurations A, Bronzinus turbine, B, Cardiff University (CU) turbine rotor, C, Flipwing turbine, D, hunter turbine, E, Deflector blade turbine (DBT) turbine, F, Tideng turbine [Colour figure can be viewed at wileyonlinelibrary.com]…”

“…The illustrative view of the working of DBT is shown in Figure E. It was mainly designed to harness the hydrokinetic potential of tidal and ocean current …”

“…In order to have a comparative performance analysis of DBT and fixed blade turbine (FBT), Yang et alcarried out the numerical and experimental investigations. It has been found that the power coefficient of DBT is about 41% more than the FBT.…”

Experimental investigation of Savonius hydrokinetic turbine with different flow diverting blocking plate

“…5 Kerikous et al 1 looked into irregularly formed deflector plates for the Savonius rotor and discovered that they improved the power coefficient. By introducing a deflecting bladed hydrokinetic rotor, Yang et al 18 strive to reduce retarding torque. Golecha et al 19 employed dual deflector plates at first, and they identified their best placements.…”

“…5 Kerikous et al 1 investigated unevenly shaped deflector plates for Savonius rotor and found improvement in power coefficient. Yang et al 18 try to decrease retarding torque by introducing deflecting bladed hydrokinetic rotor. Dual deflector plates were first used, and their optimum positions were determined by Golecha et al 19 Elbatran et al 20,21 provided a duct, and Yuwono et al…”
