MARTURET P, Gustavo J; GUTIERREZ, Edgar  y  CARABALLO, Simón. Fourier series to model energy potentials in helical turbines. uct [online]. 2015, vol.19, n.76, pp.118-127. ISSN 1316-4821.

Modeling and numerical simulation of a Gorlov hydrokinetic turbine are both presented using the finite volume method to obtain the fluid-dynamic behavior of the water as it passes through the turbine. A study of convergence, to make the domain meshing independent of the system properties, determines a finite volume model with a relative error of 0.5%, in quasi-stationary regime. Turbulence is simulated with the k-ε model. The characteristic curves of torque with respect to the flow velocity and the angular position of rotation about its axis are presented. The torque describes a periodic function type in the azimuthal angle sequence in both flow rate and rotational speed of the turbine, thus a Fourier series models the quantifying of the energy potential of the Gorlov turbine.
