| description | In this study, the derivation of mathematical model for the wave modulation through an incompressible
viscous fluid contained in a prestressed thin stenosed elastic tube is presented. The artery is assumed to be
incompressible, prestressed thin walled elastic tube with a symmetrical stenosis, whereas the blood is
considered to be incompressible and Newtonian fluid. By utilizing the nonlinear equations of tube and fluid,
the weakly nonlinear wave modulation in such a medium is examined. Employing the reductive
perturbation method and considering the long-wave approximation, we showed that the third-order term in
the perturbation expansion is governed by the dissipative nonlinear Schrodinger equation with variable
coefficient. Our results shown that this type of equation admits a downward bell-shape wave propagates to
the right as time increases with decreasing wave amplitude. |
