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 ...
On the derivation of some non-linear evolution equations and their progressive wave solutions
(Pergamon-Elsevier Science, 2003-06)
In the present work, utilizing the reductive perturbation method, the non-linear equations of a prestressed viscoelastic thick tube filled with a viscous fluid are examined in the longwave approximation and some evolution ...

Head-on-collision of nonlinear waves in a fluid of variable viscosity contained in an elastic tube
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-08-30)
In this work, treating the arteries as a thin walled, prestressed elastic tube and the blood as an incompressible viscous fluid of variable viscosity, we have studied the interactions of two nonlinear waves, in the long ...
Interaction of nonlinear waves governed by Boussinesq equation
(Elsevier Ltd, 2006-12)
In the present work, the nonlinear interactions of two acoustical waves governed by the Boussinesq equation with different wave numbers, frequencies and the group velocities are examined. For that purpose, we used the ...
An analytical solution to the dissipative nonlinear Schrodinger equation
(Elsevier Science, 2003-12-20)
Motivated with a solitary wave type of solution to the nonlinear Schrodinger (NLS) equation, in this work we shall seek a travelling wave solution to the dissipative NLS equation by use of the hyperbolic tangent method. ...
A note on the exact travelling wave solution to the KdV-Burgers equation
(Elsevier Science, 2003-10)
In the present note, by use of the hyperbolic tangent method, a progressive wave solution to the Korteweg-de Vries-Burgers (KdVB) equation is presented. The solution we introduced here is less restrictive and comprises ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2008-11)
In the present work, treating the arteries as a prestressed thin walled elastic tube with a stenosis and the blood as a Newtonian fluid with variable viscosity, we have studied the propagation of weakly nonlinear waves in ...
Forced KdV equation in a fluid-filled elastic tube with variable initial stretches
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-11)
In this work, by utilizing the nonlinear equations of motion of an incompressible, isotropic thin elastic tube subjected to a variable initial stretches both in the axial and the radial directions and the approximate ...
