A simplified pore-scale model for slow drainage including film-flow effects
Paula Reis, Marcel Moura, Gaute Linga +3
Film flow through networks of corners and capillary bridges can establish connections between seemingly isolated clusters during drainage in porous media. Coupled with drainage thr…
Competing gravitational and viscous efects in 3D two-phase flow investigated with a table-top optical scanner
Joachim Falck Brodin, Per Arne Rikvold, Marcel Moura +2
We present experiments and theory describing the transition from viscosity-stabilized flow to gravitationally unstable fingering for two-phase flow in a 3D synthetic porous medium.…
Stable and unstable capillary fingering in porous media with a gradient in grains size
Tom Vincent-Dospital, Marcel Moura, Renaud Toussaint +1
We present a theoretical and experimental investigation of slow drainage in porous media with a gradient in the grains size (and hence in the typical pores' throats), in an externa…
Burst dynamics, up-scaling and dissipation of slow drainage in porous media
Knut Jørgen Måløy, Marcel Moura, Alex Hansen +2
We present a theoretical and experimental investigation of drainage in porous media. The study is limited to stabilized fluid fronts at moderate injection rates, but it takes into…
Visualization by optical fluorescence of two-phase flow in a three-dimensional porous medium
Joachim Falck Brodin, Marcel Moura, Renaud Toussaint +2
Slow flow of a single fluid through a porous medium is well understood on a macroscopic level through Darcy's law, a linear relation between flow rate and a combination of pressure…
Vortex motion around a circular cylinder above a plane
G. L. Vasconcelos, M. Moura
The study of vortex flows around solid obstacles is of considerable interest from both a theoretical and practical perspective. One geometry that has attracted renewed attention re…
Verification of a dynamic scaling for the pair correlation function during the slow drainage of a porous medium
Marcel Moura, Knut Jørgen Måløy, Eirik Grude Flekkøy +1
We give experimental grounding for the remarkable observation made by Furuberg et al. in Ref. [furuberg1988] of an unusual dynamic scaling for the pair correlation function $N(r,t)…
Critical behavior in porous media flow
Marcel Moura, Knut Jørgen Måløy, Renaud Toussaint
The intermittent burst dynamics during the slow drainage of a porous medium is studied experimentally. We have shown that this system satisfies a set of conditions known to be true…
Impact of sample geometry on the measurement of pressure-saturation curves: experiments and simulations
M Moura, E. -A Fiorentino, Knut Jørgen Måløy +2
In this paper we study the influence of sample geometry on the measurement of pressure-saturation relationships, by analyzing the drainage of a two-phase flow from a quasi-2D rando…
Vortex flow around a circular cylinder above a plane
M. N. Moura, G. L. Vasconcelos
The study of vortex flows in the vicinity of multiple solid obstacles is of considerable theoretical interest and practical importance. In particular, the case of flows past a circ…
Vortex motion around a circular cylinder
G. L. Vasconcelos, M. N. Moura, A. M. J. Schakel
The motion of a pair of counter-rotating point vortices placed in a uniform flow around a circular cylinder forms a rich nonlinear system that is often used to model vortex sheddin…
Four-vortex motion around a circular cylinder
M. N. Moura, G. L. Vasconcelos
The motion of two pairs of counter-rotating point vortices placed in a uniform flow past a circular cylinder is studied analytically and numerically. When the dynamics is restricte…
