Abstract
The presented work presents a mechanic model, with strong thermodynamic basis for describing gas release and absorption in liquids media when the gas liquid mixture is submitted to changes of pressure and volume. The mixture is supposed to be comprised by a liquid with an inert gas dissolved in it, along with free gas dispersed throughout. The simplification assumptions are isothermal transformation, homogeneous mixture with no slip condition, and no surface stress between phases. The model parameters are determined with experimental data and then the model is validated through comparison with experimental results.
