Finite element solution of multi-dimensional two-phase flow through porous media with arbitrary heating conditions

Numerical simulation of complete liquid–vapour phase change process inside porous media using smoothing of diffusion coefficient

“…4 Henceforth shall be referred to as "jump" in the rest of this article. 5 Since the saturation temperature depends on the local pressure. 6 For water at 100 C, the liquid density (957.85 kg/m 3 ) is nearly 1600 times that of the vapour (0.5978 kg/m 3 ).…”

“…Thus, in this formulation, discontinuities in the diffusion coefficient are eliminated and the explicit heat diffusion occurs solely due to the temperature gradient which can play its role even in the two-phase region. 5 It is also evident that such a remedy may suffice when there is appreciable change in the local pressure, but would not possibly perform equally well for cases where the pressure gradient is not appreciable owing to the extremely low mass flow rate.…”

Modeling the Unsaturated Flow in Liquid Composite Molding Processes: A Review and Some Thoughts

“…Finally, it was shown that the generalized Darcy's law also can yield good predictions provided that two separate relative permeabilities k r are chosen for water and air. In the same spirit, the researchers may like to see if the formalism developed for the traditional multiphase flow can be applied to model resin-airflow in porous medium as well [92,93], and thus provide valuable insights in the development of a good bubble creation and migration model.…”

Characterization of Mold Filling in Vacuum Infusion Process

“…Vacuum infusion process (VIP) has been showing great potentials in many areas such as automobile, aerospace, marine, and construction industries [2][3][4]. Both the use of vacuum and the flexibility of a vacuum bag result in many advantages, which include low tooling cost, processability for complex and large parts, and reduction of labour.…”
