Image-based morphological characterization of multiphase porous media flow

PN 1-4 (II)

Project description

The main focus of the project is on the performance of advanced micro-fluidic experiments to analyse multiphase flow processes and, by using advanced visualization and image processing techniques as well as pore-scale resolved Direct Numerical Simulations (DNS) via Smoothed Particle Hydrodynamics (SPH). We strive to characterize the effects taking place at the interface between all phases, including the wetting and non-wetting phases, during drainage/imbibition cycles. The micro-fluidic experiments allow for the investigation of viscous and capillary dominated flow scenarios, in which a broad range for capillary number (Ca) and viscosity ratio (M) are employed in order to highlight their effect on the evolution of flow in a temporal and spatial manner. Furthermore, the role of the flow domain geometry in the evolution of flow, will also be investigated for the above-mentioned combinations of boundary conditions and physical fluids’ properties. A number of flow domains with similar average properties will be evaluated with respect to the corresponding Representative Elementary Volume (REV). The advantage of having a high temporal and spatial resolution from the experimental setup, will serve in the favour of time-dependent investigations of relaxation aspects of interfacial area. Incorporating simulations into our methodology will serve as a valuable complement to image-based techniques, offering a more comprehensive understanding, e.g. by providing locally resolved pressure fields. Moreover, simulations present a unique opportunity to explore Ca and M regimes that lie beyond the experimental feasibility. The dataset obtained from PN1-4 serves as a robust foundation to analyze key aspects governing the dynamics of multi-phase flow.
