This paper describes a study of different designs for the wind turbine. The basic wind turbine configuration with a second smaller rotor mounted in the front of the main rotor to extract as much force as possible from the flow. The wind turbine used in all the simulations was an upwind turbine with a 3 MW horizontal axis. The behaviors of pressures, velocities, and power generated were simulated and discussed. Three different configurations have been designed and simulated in SolidWorks at four different wind velocities ranging from 10 to 40 mph with an increment of 10 mph. The results revealed that the power generated by the rotor of the dual turbine to the rotor of the conventional turbine, the power created by the conventional turbine’s rotor is higher even though the size is the same. Furthermore, adding a diffuser equipped with a plat-type circular frame achieved the best performance. Finally, some numbers and figures are highlighted, and a conclusion is stated to summarize the results.
