Balance laws in fluid mechanics, geophysics, biology (theory, computation, and application)

The registration is closed. 

The balance principle appears as a fundamental modeling tool in a  wide range of applications. In realistic applications, such as gravitational flows, hydrology, biological complex fluids, it results in highly nonlinear partial differential equations, including stiff source terms and nonconservative products, and involves multiple time and space scales. This leads to serious challenges, from both the mathematical modeling and numerical viewpoints. The aim of this conference is to bring together researchers from various domains, to discuss recent progresses in these directions, and foster interactions between disciplines to tackle new challenges.

Hôtel Dupanloup : 1, rue Dupanloup - 45000 ORLEANS - FR

The conference venue is unique. Located right next to the Orléans’ cathedral, the episcopal palace of Orléans, built between 1635 and 1641, locally known as the Hôtel Dupanloup, is a classical French building which served until 1905 of residence to the bishops of Orléans.  Since 2014, the renewed palace hosts the International University Center for Research and Le Studium Loire Valley Institute for Advanced Studies.

Participants will be welcomed in this exceptional surrounding, blending Middle Age and Renaissance cultures with modern design and will have the opportunity to discover French cuisine and wines.
