Numerical simulations of the fluid flow around a small rotating vertical axis wind turbine are performed using a time accurate Reynolds Averaged Navier Stokes (RANS) solver. A moving mesh technique is applied for the simulation of the rotating wind turbine. The RANS equations are then formulated in ALE. All computations are performed assuming 2D incompressible fully turbulent flow. Turbulence is modelled by the SST k/ω model of Menter.Blade forces and torque are obtained from the solution of the RANS equations by integrating the pressure and shear stress over the blade surface. The expected wind turbine output is determined at given rotational speeds. The resulting power coefficients are compared to that obtained by applying a multiple stream tube theory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
