Numerical simulation

Numerical simulations describe the ascent and evolution of a hot multi-phase and multi-component fluid, made of water and carbon dioxide, through a homogeneous porous medium.

Selected system properties and conditions allowed the reproduction of some of the main features characterizing the natural system, including the energy budget associated with the ascent and condensation of hot fluids, and the development of a single-phase gas region, whose existence had been inferred based on independent chemical data (Fig. 48).
