About the Multidisciplinary Seminar Program

Created in 1995, the Escola Tecnica Superior d'Enginyeria Quimica (ETSEQ) at Universitat Rovira i Virgili aims at becoming an international reference in chemical engineering education and research. The ETSEQ is located in an area that is socially and economically very dynamic, and that is home to one of the most important centers of chemical industry in southern Europe.

The Multidisciplinary Seminar Program is both the seminar series for faculty and researchers in the ETSEQ, and a mandatory class for its graduate students. The Program aims at inviting leading international researchers working on areas that are of interest to faculty and researchers in the School.

Next seminar (April 26, 2019)

Different type of derivations of the Smoothed Particle Hydrodynamics equations for solving free-surface flows (Andrea Colagrossi)

Location: Sala de Graus, ETSEQ
Start time: 12 p.m.

Abstract:

The presentation is dedicated to 20-years of developments, studies and applications of the Smoothed Particle Hydrodynamics (SPH) method in the fluid mechanics field. Within this method the fluid is modelled as a macroscopic systems of discrete particles, which dynamic equations can be derived rigorously through Lagrangian mechanics. The SPH was invented in 1977 to simulate astrophysical problems. After 40 years of studies and developments this meshless method is now becoming widely used in different Engineering fields. In the last decade this particle method was successfully applied in fluid dynamics problems characterized by large deformation of interfaces such as: simulations of violent free-surface flows, multi-phase flows, flows around deformable bodies, etc. Furthermore, the SPH method has also been used profitably by computer graphics studios for special effects of movie sequences and for the improvement of virtual and augmented reality frameworks. During the presentation a brief recall of the history of the SPH will be given, underlying the peculiarities of this particle method and its theoretical background, and highlighting the main differences with respect to other classical mesh-based CFD methods.
