Computational fluid dynamics simulation of the aerodynamics of a high solidity, small‐scale vertical axis wind turbine

ABSTRACT A computational fluid dynamics simulation was performed for a small‐scale, high solidity ( σ = 0.48) H‐type Darrieus vertical axis wind turbine. Two‐dimensional unsteady Reynolds‐averaged Navier–Stokes equations were solved for the turbine numerical model, which has a large stationary domain and smaller rotating subdomain connected by a sliding mesh interface. The simulation results were first validated against steady‐state airfoil …
