the transport of dissolved contaminants in groundwater is usually described by the advectiondispersion equation with reaction. several numerical methods for solving the one-dimensional are availableincluding finite difference methods, finite volume methods, and finite element methods. stringent conditions,such as small peclet (pe) and courant (cr) numbers, must be satisfied to ensure the accura...

We provide a s:lfstemat.1c analysts of thl:: consistency. stability. convergence and accuracy of the numerical solution of the transport equation by a general Eulerian-Lagrangian Method (ELM). Tbe method involves three basic steps: the backwards trackln~ of characteristIc lines follo\1ing the flow. the interpolation of concentrations at the feet of these lines. and the solution of dispersion ta...

In this paper, we perform a systematic multiscale analysis for convection dominated transport equations with a weak diffusion and a highly oscillatory velocity field. The paper primarily focuses on upscaling linear transport equations. But we also discuss briefly how to upscale two-phase miscible flows, in which case the concentration equation is coupled to the pressure equation in a nonlinear ...

Let's read! We will often find out this sentence everywhere. When still being a kid, mom used to order us to always read, so did the teacher. Some books are fully read in a week and we need the obligation to support reading. What about now? Do you still love reading? Is reading only for you who have obligation? Absolutely not! We here offer you a new book enPDFd spectral elements for transport ...

Abstract Ultrafast X‐ray diffraction is used to quantify the transport of energy in laser‐excited nanoscale gold–nickel (Au–Ni) bilayers. Electron and efficient electron–phonon coupling Ni convert laser‐deposited conduction electrons within a few picoseconds into strong non‐equilibrium between hot cold Au phonons at bilayer interface. Modeling subsequent equilibration dynamics various two‐tempe...
