SFB 1313 doctoral researcher Kilian Weishaupt from the Department of Hydromechanics and Modelling of Hydrosystems (LH2) successfully defend his PhD thesis “Model Concepts for Coupling Free Flow with Porous Medium Flow at the Pore-Network Scale: From Single-Phase Flow to Compositional Non-Isothermal Two-Phase Flow". Congratulations Kilian, we are so proud of you!
Kilian Weishaupt completed his PhD within SFB 1313’s Integrated Research Training Group "Interface-Driven Multi-Field Processes in Porous Media".
Abstract
Coupled systems of free flow adjacent to a porous-medium appear ubiquitously in nature and intechnical applications. Examples for interface-driven transport and exchange processes includesoil evaporation, fuel cell water management or food drying. Understanding the complexity of pore-scale mechanismsis paramount to build efficient and reliable mathematical and numerical models. Typically, averaged models based on the concept of a representative elementary volume (REV) approach are chosento overcome the enormous computational demand of solving these types of systems on the pore scale.This leads, however, to a loss of detail for certain sub-scale processes which might critically affect the global system behavior.
