Comparison of Mixing Plane, Frozen Rotor, and Sliding Mesh Methods on a Counter-Rotating Dual-Rotor Wind Turbine

Nowadays, there are numerous new features available in CFD (computational fluid dynamics) that can simulate complex physical phenomena, which used to be challenging address. However, current software, certain problems simulated using different approaches. In our article, we chose rotating motion methods analyze a counter-rotating dual-rotor wind turbine (CO-DRWT). Using the approaches selected (mixing plane, frozen rotor, and sliding mesh), examined torque on rotors compared them. The following conclusion was reached. If transient flow must examined, then mesh method provided most realistic results, while rotor adequate if investigated effect of wake vortex near blades or its environment. mixing plane should when focus is kinetics kinematics blade structure.
