Enhanced Disk Actuator Modeling

Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for modeling turbine parameters. One of the methods includes obtaining, along multiple points of a blade of a turbine from a minimum radius rmin of the blade to a maximum radius rmax of the blade, lift coefficients Cyi and drag coefficients Cxi. At the multiple points of the blade from rmin to rmax, corresponding components of an upstream fluid flow velocity vector uh,Ri and uφ,Ri and components of a downstream fluid flow velocity uh,Li and uφ,Li are obtained. Averaged directions βi of the upstream and downstream fluid flow velocity vectors are computed using the components of the upstream fluid flow velocity vector uh,Ri and uφ,Ri and the components of the downstream fluid flow velocity uh,Li and uφ,Li. The total torque M of the turbine is computed including summing, from rmin to rmax, (Cxi sin βi+Cyi cos βi).
