Computer simulations reveal the existence of the two limiting propagation modes observed in recent experiments with liquid phase isothermal reactions. These two modes respectively correspond to a wrinkled although sharp propagating interface and to a broadened one. Specific laws relative to the enhancement of the front velocity in each regime are confirmed by our simulations. 2011-07-07T12:52:16Z 2011-07-07T12:52:16Z 1997 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: http://dx.doi.org/10.1103/PhysRevE.56.1729 Physical Review E, 1997, vol. 56, num. 2, p. 1729-1732 http://dx.doi.org/10.1103/PhysRevE.56.1729 (c) The American Physical Society, 1997 info:eu-repo/semantics/openAccess The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
