Stiriba, Youssef

I am currently a researcher and associate professor in the Department of Mechanical Engineering at the Rovira i Virgili University in Tarragona. I obtained my PhD in CFD (Computational Fluid Dynamics and Numerical Analysis) in 2000 at the University of Valencia. Then I did a postdoctoral stay, in the period 2000-2001, at the CERFACS Institute (Centre de Formation Avancée dans le Calcul Scientifique) in Toulouse (France), and a research stay, in the period 2002-2004, at the University of Technology RWTH-AACHEN in Aachen (Germany). I started my research with the development of finite volume methods for compressible flows based on eulerian systems with general equations of state and the study of some numerical pathologies of hyperbolic systems, during my thesis in Valencia. Later, during my postdoctoral stay at the CERFACS Institute, my research focused on AEDS and Airbus engineering problems, especially subsonic and supersonic, flow around three-dimensional configurations, using the NSMB multi-block flow solver (see http://www.cerfacs.fr). As a researcher at the University of Technology RWTH-AACHEN, I extended my research areas to problems of fluid-structure interaction, adaptive mesh refinement strategies and accelerative techniques in the context of the SFB 401 cluster project led by the German Science Foundation (DFG). Also during this period I was fully involved in the research process at the level of preparation of project proposals and supervision of the research carried out by students. Since then I have been reviewing articles for two international journals in my research area. I am currently working on different research projects, all of them financed with public funds. These are projects oriented to the development of new flow solvers, based on Navier-Stokes, using unstructured meshes for DNS and LES, as well as for the study of some relevant problems on heat transfer and multiphase flows in biochemical reactors, heat transfer and mass through membranes. Research includes understanding and prediction of nonlinear fluid-structure interactions, nonlinear instabilities, transition to turbulence, implementation of new finite volume methods using oriented object concepts and unstructured meshes. I am currently teaching undergraduate courses in Fluid Mechanics in Mechanical Engineering and Numerical Methods in Chemical Engineering. I also teach at the CERFACS Institute, the University RWTH-AACHEN, and the University of Washington.
