4. Contribution of modeling

As highlighted in paragraph 3 , it is possible to highlight some analytical solutions for foam expansion under very restrictive assumptions and very simple geometries. In particular, this type of analytical solution does not incorporate strong thermomechanical couplings or the explicit dependence of rheology on chemical kinetics. However, it is possible to go further by describing the thermodynamics of reactions, and using numerical simulation,...
