Acoustic Response of Fluid Adsorption and Transport in Nanoporous Materials: Molecular Simulation and Theory
Fluids within nanoporous materials are the topic of intense research to unravel the impact of nanoconfinement and surface forces on fluid thermodynamics and dynamics. From a practical viewpoint, such nanconfined fluids are at the heart of efficient technologies impacting our economy/ecology: energy storage/conversion, environment protection, health/human welfare, agribusiness/food science, etc. In particular, adsorption and separation in nanoporous solids are expected to address increasingly complex problems such as bio/agropollutants removal, greenhouse gas mitigation, drinkable water production, etc.
In this PhD thesis, we will employ classical molecular modeling and theoretical approaches – from the atomic to the macro scales – to unravel the acoustic signature of adsorption/transport in nanoporous materials. At each scale, we will probe spontaneous acoustic emission by the fluid/solid system and its response to acoustic wave stimulation. Comparison with experiments done in our group and in the context of a national research project will be performed at each scale. Fluids with different interactions (He, CH4, CO2) will be studied in nanoporous materials to probe pore size/interaction effects. By varying, statically or dynamically, the pressure gradient inducing flow and the mean pressure/temperature, the role of transport type (Knudsen, diffusion, viscous flow) and adsorption type (partially and entirely filled pores) will be probed
