An improved model to evaluate thermodynamic solar plants with cylindrical parabolic collectors and air turbine engines in open Joule-Brayton cycle

► An improved model to calculate an innovative CPS solar plant is presented. ► The plant works with air in an open Joule-Brayton cycle. ► The reheating of the air increases the thermodynamic efficiency. ► The plant is very simple and competes well with other more complex solar plants.
