An automated strategy for gas turbines off-design predictions with a CFD-based throughflow method

•A strategy for the off-design analysis of gas turbines is proposed.•The method is based on a CFD-based throughflow method.•A modern four-stage cooled gas turbine is considered for validation.•Off-design predictions compare very well with 3D CFD results.•A complete operating map of the turbine can b...
