Weakly nonlinear waves in elastic tubes filled with a layered fluid
(Freund Publishing House, 2002)
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 ...
Waves in an elastic tube filled with a heterogeneous fluid of variable viscosity
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-07)
By treating the artery as a prestressed thin elastic tube and the blood as an incompressible heterogeneous fluid with variable viscosity. we studied the propagation of weakly non-linear waves in such a composite medium ...
Modulation of nonlinear waves in a thin elastic tube filled with a viscous fluid
(Pergamon-Elsevier Science LTD., 1999-11)
In the present work, utilizing the nonlinear equations of a prestressed thin elastic tube filled with an incompressible viscous fluid the propagation of weakly nonlinear waves in such a medium is studied. Considering that ...
An application of multiple-time scale perturbation method to nonlinear ion-acoustic waves
