Fluid flows around turbomachinery using an explicit pseudo-temporal Euler FEM. (English) Zbl 0818.76044

Summary: This work is devoted to the simulation by finite elements of nearly incompressible inviscid flows in real three-dimensional geometries, by means of an Euler code based on the streamline upwind Petrov-Galerkin method, explicit forward Euler pseudo-temporal time integration and periodic and absorbing boundary conditions, among other features. The main goal is 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.
