Generalized diffusion-advection schemes and dispersive sedimentation: A fractional approach
We consider advection processes following anomalous statistics on an effective transport level, within the framework of fractional kinetic equations. We discuss different realistic situations such as Galilei variant and invariant advection, as well as dispersive sedimentation processes. Exact analytical solutions for the plume and the moments characterizing these transport processes are calculated. We introduce an estimation for the breakthrough of the tracer in the dispersive processes.
