Arctic Pores
The Arctic is a complex environment, with porous media forming parts of the lithosphere, cryosphere, hydrosphere, and biosphere. In this talk, we present our work on the mathematical and computational modeling of phenomena of energy and mass transport, as well as of mechanical deformation in the Arctic soils; these are coupled to the processes in the atmosphere controlled by the Earth’s climate and weather.
What Will You Learn?
In this webinar, we will begin by exploring heat conduction and water flow involving the ice/water phase transitions in permafrost soils coupled to the processes in the snow cover. While many aspects have been well studied by geophysicists using Darcy scale models based on empirical data, our approach works in silicio, aiming to find explanations and interpretations for these models starting at the pore-scale and scaling up.
We will also outline the principles of robust and efficient computational algorithms for simulations from the pore- to the Darcy scales. Finally, we will illustrate how these efforts can be used to build more and better models, which is also important for applications beyond the Arctic, such as in biological tissue and extraterrestrial materials.
This work represents a joint effort with an incredible team of students and collaborators, who will be duly acknowledged in the presentation.
