Abstract:
We analyze pulse interaction in active-dissipative systems that arise in the study of falling liquid films in the presence of various external effects, e.g. an applied electric field or turbulent gas flow. Such effects result in additional non-local terms in the form of pseudo-differential operators. We analyze both weakly nonlinear and fully nonlinear reduced model equations. We compare the theoretical predictions with numerical results for reduced model equations and Stokes flow. It is found that non-locality strongly influences pulse interactions and results in several features that are not present in local equations.Download:Talk_1030930.doc
