Analyse et simulation de l'influence de la température et de la pression sur les coefficients de transport du CO2 dans du PVDF

Abstract

Simulation of Temperature and Pressure Influence on Transport Coefficients of CO2 in PVDF — This work is dedicated to the optimisation of gases transport coefficients in polymers. It consists in modelling the influence of the temperature and pressure on the diffusion coefficient. This model is validated by optimisation on the CO2-PVDF system. A pressure quadratic model generalising existing works is proposed. It describes in particular the effect of high pressures on the transport coefficients.
