Накратко на български

Потоците от течности и разпространението на вещества в частично наситени порести среди, като например почви, се анализират чрез нови модели. Това помага за по-точното предсказване на движението на нереактивни разтворени вещества в сложни геологически структури.

A Novel Framework Predicting Steady Flow and Solute Transport in Partially Saturated, Heterogeneous Media.

USFT set out to improve our understanding and quantifying abilities of flow, transport, and reaction processes in partially saturated heterogeneous media and their consequences on the relevant Darcy-scale for different multiphase conditions and flow dynamics, which is one of the leading open challenges in porous media research. In this project, we developed a novel framework to predict flow & transport processes at the micro and Darcy scales, in partially saturated media, from the basic pore structure parameters and general flow dynamics. First, we developed a new image analysis method and used it to analyze several experimental results of multiphase flow under different flow conditions in a multifluidic device. This study provided new insights into the interplay between stable and unstable processes in multiphase systems on the most basic pore system features (waterfilled pore size distribution, displacement mechanism, and velocity distribution). Furthermore, we used the image analysis method to extract different levels of phase configuration to construct network models of different complexity to evaluate the permeability, velocity distribution, hydraulic tortuosity, and dead-end (stagnant phase) fraction. As discussed in the following, these parameters are the minimal information needed to predict the complex non-Fickian transport in partially saturated media accurately. Second, we developed a Lagrangian CTRW upscaling framework for partially saturated media. This framework uses the velocities distribution, hydraulic tortuosity, and the fraction of stagnant dead-end phase to predict the breakthrough curve of non-reactive solutes. These accomplishments and their integration allow us to characterize diverse flow regimes in heterogeneous media within a unique, entirely predictive template (i.e., not parameterized by the transport parameters or the spatial pore-scale flow field). This interdisciplinary endeavor incorporates particle dynamic models, stochastic methods, CFD models, and analysis of microfluidic device experiments and numerical direct pore simulations

Цел на проекта

Understanding and quantifying flow, transport, and reaction processes in partially saturated heterogeneous media and their consequences on the relevant Darcy-scale for different multiphase conditions and flow dynamics, remains one of the leading open challenges in porous media research. In this project, we develop a novel framework to predict flow & transport processes at the micro and Darcy scales, in partially saturated media, from the basic pore structure parameters and general flow dynamics. Flow & Transport processes in heterogeneous multiphase media span a variety of disciplines: physics, chemical engineering, environmental practices, geology, agriculture, microbiology, petroleum recovery, to name a few. This project novelty advances current knowledge on several lines. First, we will renew our current perception of the interplay between stable and unstable processes, in multiphase systems, on the most basic pore system features (water-filled pore size distribution). Second, we will develop a Lagrangian CTRW upscaling framework to partially saturated media. These accomplishments and their integration will allow us to characterize diverse flow regimes in heterogeneous media within a unique template that is entirely predictive (i.e., not parameterized by the transport parameters or the spatial pore-scale flow field). This interdisciplinary endeavor incorporates particle dynamic models, macroscale stochastic methods, CFD models, and meta-analysis of microfluidic devices experiments and numerical direct pore simulations. To this end, the project will draw from the complementary skills of the supervisor and the researcher. In this context, this action is fully compatible with the MSCA Work Programme goals: • high-quality researchers’ training and supervision • strengthening research capacity • providing fairer and more attractive working conditions • building new and sustainable international and inter-sectoral partnerships and networks.
