报告内容摘要：
In recent decades, there have been major advances in experimental techniques for pore-scale studies of fluids flow and mass and heat transport in porous media. An effective and highly popular method is the use of micromodels, which allow direct observation of flow and transport on the pore scale, and thus help to increase our insight of flow and transport phenomena on both micro and macro-scales.
A micromodel is an artificial representation of a porous medium, made of a transparent material. In our studies, we have used Poly-Di-Methyl-Siloxane (PDMS), which is a viscoelastic, silicon-based organic polymer. It is optically transparent, inert, non-toxic, and non-flammable. We have studied capillary phenomena, colloid transport, and heat transfer during two-phase flow. We have shown that capillarity phenomena are controlled by fluid-fluid interfaces at the micro-scale. Phenomena such as Haines jump, snap off, and local drainage during imbibition can be clearly seen. We have used our results to produce macroscale data and test our Darcy scale models.
In colloid transport experiments, we directly observe colloids movement, their retention at solid-fluids and fluid-fluid interfaces, and their remobilization with the moving interface and contact lines. We have also performed kinetic heat transport experiments where the two fluids have distinctly different temperatures at the pore scale. Under such conditions, fluid-fluid interfaces play a major in heat transport processes. Our results are relevant for understanding processes in oil and gas reservoirs, soil and groundwater remediation. CO2 sequestration in geological formations, energy storage operations, and deep geothermal systems.
