    Design of a new hydrokinetic turbine simulation model based on the extended power coefficient concept by Manuel Rico-Secades, Antonio Javier Calleja-Rodríguez, Aitor Fernández-Jiménez, Eduardo Álvarez-Álvarez, Fher Said Macedo-Garcia, Jaime Arau-Roffiel

    Published 2025-04-01
    “…The operation of hydrokinetic turbines under blockage conditions causes situations where the classical power coefficient does not adequately explain their energy extraction, often exceeding Betz’s limit, as it is referred only to the kinetic energy of the water flow in open field or without boundaries. The research presented defines the extended power coefficient as the fraction of the energy available, including kinetic and potential energy, obtained by the turbine in a rectangular water channel. …”
