Abstract
We consider a sharp-diffuse interfaces seawater intrusion model [3] in
coastal aquifers. This process leads to a coupled system of two nonlinear parabolic partial differential equations simulating two immiscible fluids considering the dynamics of transition zones.
To the discretization in time, we apply a cell-centred Multi-Point Flux Approximation (MPFA-O) finite volume...
In the field of nuclear energy, computations of complex two-phase flows are required for the design and safety studies of nuclear reactors. In general, there exists two families of numerical methods for the simulation of two-phase flows. Firstly, colocated schemes ([2]) are usually used on unstructured meshes where the unknowns are located in the same place (cell-centered). On the other hand,...
Le problème physique concerne la propagation d'ondes scalaires dans le cadre de l'élasticité linéaire anti-plane en 2D à travers une rangée périodique d'inclusions
In this talk we present a nonlinear mathematical model of a particular wave energy converter, the so-called oscillating water column. In this device, waves governed by the one-dimensional nonlinear shallow water equations arrive from the offshore, encounter a step in the bottom topography and then arrive into a chamber to change the volume of the air to activate the turbine. The system is...
