Exchange processes across a porous-media free-flow interface occur in a wide range of environmental, technical and bio-mechanical systems. In the course of these processes, flow dynamics in the porous domain and in the free-flow domain exhibit strong coupling, often controlled by mechanisms at the common interfaces. Therefore, understanding the underlying processes is decisive. The primary objective of this research is to analyse and improve theories of non-isothermal, multiphase, multi-component flow processes at a porous-media free-flow interface and their influence on flow in the porous media system.
The goal is to transfer the knowledge gained through the analysis of experimental and simulation data into an efficient multi-scale modelling approach using a dispersion concept where turbulence-related processes are accounted for in ample detail while still retaining a degree of efficiency, allowing for the simulation of real-world applications. To this end, it is crucial to first identify and understand the system-governing phenomena and processes observable from detailed simulations and experimental data. With the help of machine learning algorithms, these findings shall then be incorporated into advanced parametrisations or used in order to extend existing balance equations.
