Abstract

A multidisciplinary optimization procedure for gas turbine blade design has been developed and demonstrated on a generic blade. The blade is cooled both internally and externally (film cooling). Aerodynamic and heat transfer design objectives are integrated along with various constraints on the blade geometry. The blade surface geometry is defined by Bezier-Bernstein polynomials. A comprehensive 3-D Navier-Stokes equation solver is used for flow field evaluation and finite element method is used to obtain the blade interior temperatures. The average blade temperature and maximum blade temperature are minimized, with aerodynamic and geometric constraints on the blade. The constrained multiobjective optimization problem is solved using the Kreisselmeier-Steinhauser (K-S) function approach. The results for the numerical example show significant improvements after optimization.
