Small Darrieus hydrokinetic turbines with fixed pitch blades typically suffer from poor starting torque, low efficiency … helical blades, or reduced by using multiple blades. Starting torque can be marginally improved by the use of cambered blade …

different hydrokinetic turbine rotors (hybrid and single Darrieus) are evaluated in term of performance and flow across the … hydrokinetic turbine and yields about 9.9% higher power coefficient (CP) than single Darrieus rotor. The average torque coefficient …Hydrokinetic turbine technology is an emerging field to produce clean energy from the riverine systems. Lot of …
