MATHEMATICAL MODELING OF SUPERCRITICAL MULTICOMPONENT REACTIVE FLUIDS

Autor: Vincent Giovangigli, Lionel Matuszewski

Publikováno v: Mathematical Models and Methods in Applied Sciences. 23:2193-2251

We investigate a system of partial differential equations modeling supercritical multicomponent reactive fluids. These equations involve nonideal fluid thermodynamics, nonideal chemistry as well as multicomponent diffusion fluxes driven by chemical p

Structure of entropies in dissipative multicomponent fluids

Autor: Vincent Giovangigli, Lionel Matuszewski

Publikováno v: Kinetic & Related Models. 6:373-406

We investigate the structure of mathematical entropies for dissipative multicomponent fluid models derived from the kinetic theory of gases. The corresponding governing equations notably involve nonideal thermochemistry as well as diffusion fluxes dr

Combustion Theory and Modelling, Taylor & Francis, 2016, ⟨10.1080/13647830.2016.1150518⟩

International audience; We present a diffuse-interface all-pressure flame model that transitions smoothly between subcritical and supercritical conditions. The model involves a non-equilibrium liquid/gas diffuse interface of van der Waals/Korteweg ty

Supercritical fluid thermodynamics from equations of state

Publikováno v: Physica D: Nonlinear Phenomena. 241:649-670

Supercritical multicomponent fluid thermodynamics are often built from equations of state. We investigate mathematically such a construction of a Gibbsian thermodynamics compatible at low density with that of ideal gas mixtures starting from a pressu
