Horizontal axis wind turbines suffer from aerodynamic inefficiencies in the blade root region (near the hub) due to several non-aerodynamic constraints. Aerodynamic interactions between turbines in a wind farm also lead to significant loss of wind farm efficiency. We have developed a new dual-rotor wind turbine (DRWT) technology that aims to mitigate these two losses. One DRWT has been designed using an existing turbine rotor (the NREL 5 MW turbine) for the main rotor. The secondary rotor of the DRWT has been designed using a very high lift-to-drag ratio airfoil. Reynolds Averaged Navier-Stokes computational fluid dynamics simulations have been used to optimize the turbine design. Large eddy simulations confirm the potential of the DRWT to enhance energy capture.
