Moving reference frame and arbitrary Lagrangian Eulerian approaches for the study of moving domains in Typhon

Among the various possible methods for treating moving domains in Computational Fluid Dynamics (CFD) studies, the Moving Reference Frame (MRF) and Arbitrary Lagrangian Eulerian (ALE) approaches are being extensively studied, developed and tested in Typhon, a three dimensional unstructured cell-centered finite volume parallel CFD solver written in Fortran(90/95) and freely available on the SourceForge open source web portal. Even if the selected and developed versions are among the basic and simplest availables, signi cant functionality improvements to the solver are achieved without invasive changes to the original code and causing a minimal computational burdening. The evalued test cases show positive correspondence to the known exact solutions, a part from expected surmountable anomalies that appear using particular numerical schemes. A considerable degree of freedom is also left for further developments.
