Abstract
Wind turbines play a key role in sustainable energy production, and rotor configuration significantly influences performance. This paper presents a simulation-based comparative review of Single Rotor (SR) and Dual Rotor (DR) Horizontal-Axis Wind Turbines (HAWTs). Using computational fluid dynamics (CFD) methodologies reported in existing literature, the study evaluates parameters such as torque, power output, wake behavior, and power coefficient. Simulation studies consistently show that the DR configuration extracts more energy from the wind stream due to its ability to utilize the wake of the upstream rotor. The DR system shows power improvements ranging from 7% to 43% depending on design and operating conditions. This review consolidates the simulation findings, modeling approaches, aerodynamic considerations, and performance advantages of dual rotor systems compared to single rotor turbines
