An optimal wind turbine configuration has been identified by using dual rotor wind turbine (DRWT) technology with a novel blade design known as the humpback blade, which is inspired by the fins of humpback whales. This design features tubercles and ridges along the leading edge that extend over the last third of the blade's length.
To enhance the performance of wind turbines, this study investigates the integration of two wind energy harvesting systems. An optimal wind turbine configuration has been identified by using dual rotor wind turbine (DRWT) technology with a novel blade design known as the humpback blade, which is inspired by the fins of humpback whales.
An increase of 60 % in power output compared to single rotor wind turbines has been reported. The power coefficient was found to increase by 7.2 % compared to single rotor wind turbines. It is stated that dual rotor wind turbines have higher efficiency than conventional turbines, but the blade design and positioning need to be optimised.
The rated speed for the wind turbine is taken 10m/s. Cut in speed is about2.5m/s and Cut out speed is taken 25m/s. Lot of research has been done in application of gearless drive in dual rotor wind turbine but few researches has been done in application of mechanical gearbox in dual rotor wind turbine. .
The results validated the benefits of the humpback blade design in dual rotor systems, where the new design enhanced the lift‐to‐drag ratio in both upwind and downwind positions, resulting in higher
Realizable k-shear stress transport turbulence models are used to solve the three-dimensional, turbulent, stable, and incompressible flow equations for the performance of dual-rotor

This research reveals the regulation law of rotor spacing on aerodynamic interference effects, provides key parameter basis for optimizing wind energy capture and designing structural
Dual-Rotor Wind Turbine Horizontal axis wind turbines suffer from aerodynamic inefficiencies in the blade root region (near the hub) due to several non-aerodynamic constraints.
Conventional horizontal axis wind turbines (HAWT) consist of a single rotor and 3 blades mounted in front of the turbine. According to the Betz limit, the theoretical maximum power coefficient

Subsequently, a horizontal axis counter-rotating dual-rotor turbine (CO-DRWT) and a horizontal axis single-rotor wind turbine (HAWT) were compared by computational fluid dynamics simulation (CFD).
The captured wind energy is transformed into high speed rotational energy by transmission system. In this Wind turbine the radius of the wind blades for the dual rotor is taken as
