Recent studies have evoked heated debate about whether biologically generated (or
biogenic) fluid disturbances affect mixing in the ocean. Estimates of biogenic inputs have …

The classical Fickian model for solute transport in porous media cannot correctly predict the
spreading (the dispersion) of contaminant plumes in a heterogeneous subsurface unless its …

Recent observations of biologically generated turbulence in the ocean have led to
conflicting conclusions regarding the significance of the contribution of animal swimming to …

This paper theoretically describes and experimentally verifies two mechanisms leading to
longitudinal dispersion of a passive tracer in a random array of circular cylinders. We focus …

In this work, we use the method of volume averaging to determine the effective dispersion
tensor for a heterogeneous porous medium; closure for the averaged equation is obtained …

The understanding of the dynamics of Lagrangian velocities is key for the understanding
and upscaling of solute transport in heterogeneous porous media. The prediction of large …

Flow of uniform mean velocity U takes place in a formation of spatially variable, random
conductivity K (x). Advective transport of a plume of an inert solute is investigated by the …

Conformal map** has been applied mostly to harmonic functions, ie solutions of Laplace's
equation. In this paper, it is noted that some other equations are also conformally invariant …

We consider the stirring of an inviscid fluid caused by the locomotion of bodies through it.
The swimmers are approximated by non-interacting cylinders or spheres moving steadily …

In this work, we upscale a pore-scale description of mass transport in a porous medium
containing biofilm to develop the relevant Darcy-scale equations. We begin with the pore …
