Uphill solitary waves in granular flows.
E. Martínez,Carlos Pérez-Penichet,Oscar Sotolongo-Costa,O. Ramos,Knut Jørgen Måløy,Stéphane Douady,Ernesto Altshuler +6 more
TL;DR: Solitary fluctuations appear on the flowing layer of a heap and move "up the hill" (i.e., against the direction of the flow) as the heap reaches the open boundary.

Structure formation and instability in a tube of sand.
TL;DR: A new instability in the combined flow of fine grains and gas is investigated by means of experiments, simulations, and analytic techniques, and the simulations and experiments agree on the quantitative level.

Diffusion-limited-aggregation-like displacement structures in a three-dimensional porous medium
TL;DR: A modified version of the DLA model describes quite well the dynamics of the viscous fingering instabili11 the structure of the displacement fronts is fractal, consistent with results for the diffusionlimited aggregation (DLA) model.

Flow paths in wetting unsaturated flow: Experiments and simulations
TL;DR: The model, which couples the well established invasion percolation model for capillary governed flow with a model that describes the viscous film flow in partially filled pores, corroborates these experimental findings and reveals that the fluid pathways contain an internal link-blob structure and increase in width with decreasing gravity.

Effects of Pressure Oscillations on Drainage in an Elastic Porous Medium
Mihailo Jankov,Grunde Løvoll,Henning Arendt Knudsen,Knut Jørgen Måløy,Ramon Planet,Renaud Toussaint,Eirik Grude Flekkøy +6 more
TL;DR: In this paper, the effects of seismic stimulation on the flow of two immiscible fluids in an elastic synthetic porous medium is experimentally investigated, and the resulting morphology of the invading structure is strongly dependent on the interplay between the amplitude and the frequency of the applied pressure oscillations and the elasticity of the porous medium.
