Keywords: optimization, response surface, turbine duct

Design of transition ducts is an area of growing importance due to the trend of increasing the radial difference between the low- and high-pressure systems in modern turbo-fan engines. Thanks to rapid development of computer technology, computational fluid dynamics combined with the response surface method may be used for shape-optimization.
