A semi-unstructured grid generation method especially taylored for the meshing of turbomachinery blade passages and their associated cavities is presented. The method is based on a smart combination of quasi-3D methods, an ad-hoc block decomposition of the domain and a grid-based reconstruction of the computational domain.
A method for optimizing the number of airfoils of a turbine design is presented. The optimization consists of reducing the total number of airfoils meanwhile a set of geometric, aerodynamic and acoustic noise restrictions are fulfilled. It is described how is possible to reduce the problem degrees of freedom to just one variable per row. Due to the… (More)
