  • Experimental and numerical analysis of transport in saturated heterogeneous media

    Creator:
    Harrington, Stephanie J.
    Abstract:
    The conventional advection-dispersion equation cannot adequately describe all processes driving solute transport in heterogeneous systems. This dissertation focuses on the individual influences of both chemical (Chapter 2) and physical processes (Chapters 3 and 4) which affect solute transport. In Chapter 2 we analyzed uranium transport in natural sediment using the...

  • Advection-diffusion in inertial flow through periodically converging-diverging tubes

    Creator:
    Lambert, Adam
    Abstract:
    A direct numerical simulation of advection-diffusion in a sinusoidal tube was carried out using the commercial finite-volume code STAR-CD. The Reynolds numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers, steady-state eddies formed in the diverging sections and significantly influenced the macroscale dispersion. Long...

  • Modeling rate-limited processes along non-uniform surfaces via the method of volume averaging

    Creator:
    Lambert, Adam
    Abstract:
    Quantification of macroscale transport phenomenon in microfluidic systems is important to many science and engineering disciplines. In part, this is because fully resolved solutions to microscale balance laws over large domains are out of reach with current computational technology. Additionally, engineers are most often interested in some upscaled quantity and...
