Dr. Orestis Malaspinas, University of Geneva Bio: Dr. Orestis Malaspinas is a senior researcher in the fields of Lattice Bolzmann non-Newtonian fluids and turbulence modeling. He contributed to the Palabos software by developping advanced turbulence and turbulent boundary layer models. One of the four founding members of the company, he conducts his research activities at the University of Geneva and Université Pierre et Marie Curie (Paris) where he maintains and encourages academic contributions to the numerical models implemented in Palabos. |

Cancelled - the speaker is unwell.
The lattice Boltzmann method (LBM) has established itself as an alternative computational fluid dynamics solver since its creation in the late 80's. Historically, this numerical scheme was derived from the FHP (Frisch, Hasslacher and Pommeau) cellular automaton. In 2006, it was shown that following a rigorous procedure for the discretization of the continuous Boltzmann equation, one recovered the empirically derived LBM scheme. This important result gave a more solid theoretical basis to the method and allowed many more rigorous derivations of numerical models.
In this talk I will present recent theoretical and numerical advances in large Eddy simulation (LES) techniques using the LBM. Then I will also discuss the modeling of turbulent boundary layers and their coupling with LES. Finally I will show some other recent applications which will be selected among blood flow modeling and noise source identification.
