Abstract
The objective of this work is to clarify the role of inertial effects on the long-wavelength instabilities and dynamics of multilayer plane Poiseuille flows. A weakly nonlinear set of equations governing the evolution of interfacial waves is derived and examined. Numerical simulations show that for the flows irregular interface profiles are generic. For some systems a curious behaviour of interfaces is revealed: depending on initial conditions, interfaces evolve into irregular or soliton-like structures.
