The present work investigates the application process of non-axisymmetric endwall contouring to tandem stators, in order to improve stability and efficiency by tackling the endwall secondary flow phenomena. The present research first develops an in-house software-tool for turbomachinery stage optimization, used successively on several test cases. Non-axisymmetric endwall contouring proves to be a powerful tool for tandem vanes performance improvement, under specific conditions and within a limited range of applicability, suggesting new approaches to tandem vane designs
