Expérimental et théorique
Whether it is to purify the air of fine particle pollution or to obtain gases, our need for gas filtration and separation is growing rapidly. This need is crucial in the context of global warming and new. Aqueous foams, which are low-tec and low-cost materials can be used to separate CO2 from the other constituents of air. Indeed, they are made up of a myriad of liquid films acting as selective membranes to separate the CO2 that solubilizes in the liquid phase and the air that remains mainly in the bubbles. To advance our understanding of this problem, we propose a study of the dynamics of CO2 transfer within a foam. The proposed approach will be both experimental and theoretical. Experiments will be carried out using an existing laboratory set-up to measure how CO2 is distributed between the liquid and gas phases. Theoretical analysis will be carried out using effective medium models implemented at LIPhy.
