On well-balanced finite volume methods for non-conservative non-homogeneous hyperbolic systems
(Society for Industrial and Applied Mathematics, 2007)
In this work we introduce a general family of finite volume methods for non-homogeneous hyperbolic systems with non-conservative terms. We prove that all of them are “asymptotically well-balanced”: They preserve all smooth ...

A multilayer method for the hydrostatic Navier-Stokes equations: a particular weak solution
(Ed. Plenum Press, 2014)
In this work we present a mutilayer approach to the solution of non-stationnary 3D Navier-Stokes equations. We use piecewise smooth weak solutions. We approximate the velocity by a piecewise constant (in z) horizontal ...

Well-balanced finite volume schemes for 2D non-homogeneous hyperbolic systems. Application to the dam-break of Aznalcóllar.
(Elsevier, 2008)
In this paper, we introduce a class of well-balanced finite volume schemes for 2D non-homogeneous hyperbolic systems. We extend the derivation of standard finite volume solvers for homogeneous systems to non-homogeneous ...

An Entropy-correction free solver for non-homogeneous Shallow Water equations
(Dunod, 2003)
In this work we introduce an accurate solver for the Shallow Water equations with source terms. This scheme does not need any kind of entropy correction to avoid instabilities near critical points. The scheme also solves ...

Modelling of surface and inner wall temperatures in the analysis of courtyard thermal performances in Mediterranean climates
(Taylor and Francis, 2021)
Courtyards are an effective passive strategy for improving the energy performance of buildings. However, there is a lack of accurate simulation tools for their thermal performance due to their complex thermodynamics. ...
