Keywords: optimisation, interturbine duct, parametric design

The objective of the research is to develop a robust tool for the parametric design of S-shaped ducts. Components of the design tool are the geometry generation module, the grid generator, the CFD-solver and the optimiser. Correlations are developed, which account for the strut impact on the total pressure loss.
