S. Jespersen et al., Polymer dynamics in time-dependent Matheron-de Marsily flows: An exactly solvable model - art. no. 011801, PHYS REV E, 6301(1), 2001, pp. 1801
We introduce a model of random layered media, extending the Matheron-de Mar
sily model: Here we allow for the flows to change in time. For such layered
structures, we solve exactly the equations of motion for single particles
and also for polymers modelled as Rouse chains. The results show a rich var
iety of dynamical patterns.
