Abstract
The example of multipoint aerodynamic optimization of low pressure cylinder last stage of the steam turbine by capacity of 200 MW is considered. The weighed stage efficiency for four operating conditions of the turbine is chosen as objective function. The technology of computational investigations is based on the use of 3D flow numerical models for turbomachinery flowpaths. Searching an objective function extremum was carried out byhybridapproach, combining genetic algorithmwith localdirectsearchmethod
