  • Preparation and Properties of Porous Carbon Materials

    Creator:
    Xing, Zhenyu
    Abstract:
    Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...

  • Movement of zoospores of Phytophthora citricola in saturated porous media

    Creator:
    Ochiai, Naoyuki
    Abstract:
    The genus Phytophthora comprises numerous plant pathogens in both natural and managed ecosystems. For Phytophthora spp. that infect roots, dispersal occurs in soil water through a combination of advection and swimming of specialized motile propagules (zoospores). Specific biological and physico-chemical processes, however, remain poorly understood, due to difficulties in studying...

  • Steady-State Diffusion in a Spatially Varying Porous Medium

    Creator:
    Ferrero, Peter T.
    Abstract:
    Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...

  • Linking Pore-scale Fluid-Fluid Interfacial Curvature in Porous Media to Capillary Pressure and Local Morphology with A Novel Method for Curvature Measurement

    Creator:
    Li, Tianyi
    Abstract:
    Systems that contain multi-phase flow in porous media are of interest in diverse fields including environmental engineering, hydrogeology, and petroleum engineering etc. One of the main descriptors of multi-phase flow in porous media is the relationship between capillary pressure and fluid saturation. Capillary pressure is inherently a pore-scale variable and...

  • Pore-scale observations of three-fluid-phase transport in porous media

    Creator:
    Brown, Kendra I.
    Abstract:
    Understanding the transport of three fluid phases through porous media has important applications in subsurface contaminant remediation, oil and gas recovery, and geological CO₂ sequestration. Existing transport models may be improved by including physical phenomena that govern fluid flow at the pore scale. In particular, thermodynamic arguments suggest that hysteresis...

  • Investigation of transport phenomena in a highly heterogeneous porous medium

    Creator:
    Vogler, Daniel
    Abstract:
    This work focuses on solute mass transport in a highly heterogeneous two-region porous medium consisting of spherical low-hydraulic conductivity inclusions, embedded in a high-hydraulic conductivity matrix. The transport processes occuring in the system are described by three distinct time scales. The first time scale reflects the characteristic time for convective...

  • Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

    Creator:
    Paustian, Rebecca L.
    Abstract:
    Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recovery, CO2 sequestration, and groundwater remediation. Many studies have been performed on how two fluid phases (oil/water or air/water) behave in porous media, but very few studies exist...

  • Problems of Shape and Information in Multiscale Modeling of Transport Phenomena

    Creator:
    Ostvar, Sassan
    Abstract:
    This work is a compilation of problems that deal with multiscale analysis of transport phenomena in environmental systems. A common feature among the problems studied here is the presence of non-negligible microscale structure in various forms. Each problem is approached from the perspective that a macroscopic observable encodes aspects of...
