When Do Riemann Solutions Consist of Rarefactions, Jumps, and Constants?
Bradley J. Plohr, Stephen Schecter, Dan Marchesin
A solution of a Riemann problem for a strictly hyperbolic system of conservation laws is traditionally expected to consist of rarefaction waves, jump discontinuities, and constant…
Structure of undercompressive shock waves in three-phase flow in porous media
L. F. Lozano, I. Ledoino, B. J. Plohr +1
Undercompressive shocks are a special type of discontinuities that satisfy the viscous profile criterion rather than the Lax inequalities. These shocks can appear as a solution to…
Solving Riemann Problems with a Topological Tool (Extended version)
Cesar S. Eschenazi, Wanderson J. Lambert, Marlon M. López-Flores +3
In previous work, we developed a topological framework for solving Riemann initial-value problems for a system of conservation laws. Its core is a differentiable manifold, called t…
Vanishing adsorption limit of Riemann problem solutions for the polymer model
Yulia Petrova, Bradley J. Plohr, Dan Marchesin
We examine the vanishing adsorption limit of solutions of Riemann problems for the Glimm-Isaacson model of chemical flooding of a petroleum reservoir. A contact discontinuity is de…
