Latsuzbaia, R. (author), Negro, E. (author), Koper, G.J.M. (author)Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...conference paper 2013

Cottet, G.H. (author), Maitre, E. (author), Milcent, T. (author)An eulerian approach for fluid-structure coupling is presented for generic fluid-structure coupling an elastic body with an incompressible fluid. Fluid-solid interfaces are captured by a level-set method. The main features of the method are its simplicity, and its natural control of mass and energy. We are indeed able to prove an energy equation...conference paper 2006

Greaves, D.M. (author)This work involves the application of adaptive hierarchical grids to free surface Navier-Stokes simulation of viscous waves in a stationary tank and their interaction with a cylinder. Adapting quadtree grids are combined with a volume of fluid (VoF) approach, in which a high resolution interface capturing scheme is used for advection of the...conference paper 2006
