Özet
In this work we studied the propagation of weakly nonlinear waves in a prestressed thin elastic tube filled with an incompressible layered fluid, where the outer layer is assumed to be inviscid whereas the cylindrical core is considered to be viscous. Using the reductive perturbation technique, the amplitude modulation of weakly nonlinear waves is studied and dissipative nonlinear Schrodinger equation is obtained as the governing evolution equation. A travelling wave type of solution for this evolution equation is sought and it is shown that the amplitude of the solitary wave for the dissipative NLS equation decays in time.
