... pre-generated tuning data obtained by case-by-case shape optimization for a range of design conditions. A weighted objective function is applied to quantify both geometric and aerodynamic quality of blade sections for the optimization. Shape optimization improves output section quality by 54–87...

... at various stator inlet flow angles The robustness of the meridional shape optimization to inlet flow angle fluctuations is excellent (Fig. 20( b ) ): the optimized blade not only generates less entropy than the baseline at all incidence angles, but also the decrease in performance of the baseline...

...Romain Hottois; Arnaud Châtel; Gregory Coussement; Tom Debruyn; Tom Verstraete The present paper addresses the multi-objective aerodynamic shape optimization of the two-dimensional LS-89 turbine cascade. The objective is to minimize the entropy generation at subsonic and transonic flow conditions...

.... The optimization framework is applied to the shape optimization of two canonical steam turbine cascades, commonly referred to as White cascade and Dykas cascade . The optimization were carried out by minimizing either the liquid volume fraction downstream of the cascade or the total entropy generation due viscous...
