Gas turbine performance improvement is strictly linked to the attainment of higher maximum temperature, hence heat load management becomes an essential activity. This paper presents a decoupled procedure aimed to predict cooling performances and metal temperatures of gas turbine blades and nozzles: needed inputs are evaluated by different tools (CFD, in-house fluid network solver, thermal FEM). The procedure is validated on two different test cases: an internally cooled vane (Hylton et al.), and an internally and film cooled vane (Hylton et al.). Metal temperature and adiabatic effectiveness distributions are compared against experimental data and results from a fully 3D coupled CHT CFD analysis. © 2013 The Authors.
