This paper investigates the formulation of the optimal objective function for aerodynamic design of turbomachinery using genetic algorithms (GA) supported by Computational Fluid Dynamics (CFD). The aim is to outline entropy generation rate minimisati... Read More about Entropy generation rate optimisation for profiled endwall design for axial turbines.
