FLUID-FLOWS AROUND TURBOMACHINERY USING AN EXPLICIT PSEUDO-TEMPORAL EULER FEM

This work is devoted to the simulation by finite elements of nearly in compressible inviscid flows in real 3D geometries, by means of an Eule r code based on the SUPG (streamline upwind Petrov-Galerkin) method, e xplicit forward Euler pseudo-temporal time integration and periodic an d absorbing boundary conditions, among other features. The main goal i s the application to flow around turbomachinery, with special emphasis on the performance analysis of a given machine, that involves several numerical computations at different operation points. Finally, these results are summarized in the form of characteristic curves.
