The Riemann problem for three-phase foam flow in porous media
Luis Fernando Lozano, Grigori Chapiro, Dan Marchesin
Gas injection in the context of the three-phase flow in porous media appears in applications such as Enhanced Oil Recovery, aquifer remediation, and carbon capture, utilization, an…
On the Riemann problem for the foam displacement in porous media with linear adsorption
G. C. Fritis, P. S. Paz, L. F. G. Lozano +1
Motivated by the foam displacement in porous media with linear adsorption, we extended the existing framework for two-phase flow containing an active tracer described by a non-stri…
Traveling wave solutions for non-Newtonian foam flow in porous media
Weslley da Silva Pereira, Grigori Chapiro
The injection and in-situ generation of foam in porous media successfully control gas mobility and improve the fluids' sweep efficiency inside porous media. Mathematical models des…
Solving the inverse problem for an ordinary differential equation using conjugation
Alfaro Vigo, D. G, Alvarez +6
We consider the following inverse problem for an ordinary differential equation (ODE): given a set of data points , find an ODE $x^\prime(t) = v (x)…
Beyond the linear analysis of stability in higher derivative gravity with the Bianchi-I metric
Simpliciano Castardelli dos Reis, Grigori Chapiro, Ilya L. Shapiro
The study of stability of gravitational perturbations in higher derivative gravity has shown that at the linear level the massive unphysical ghost is not generated from vacuum if t…
