Nonlinear evolution wave equation for an artery with an aneurysm: an exact solution obtained by the modified method of simplest equation
E. V. Nikolova, I. P. Jordanov, Z. I. Dimitrova +1
We study propagation of traveling waves in a blood filled elastic artery with an axially symmetric dilatation (an idealized aneurysm) in long-wave approximation.The processes in th…

Several results from numerical investigation of nonlinear waves connected to blood flow in an elastic tube of variable radius
Zlatinka I. Dimitrova
We investigate flow of incompressible fluid in a cylindrical tube with elastic walls. The radius of the tube may change along its length. The discussed problem is connected to the…

On the variational problem for the upper bounds of solute transport in double-diffusive convection
Nikolay Vitanov, Zlatinka Dimitrova
The formulation of the variational problems for the solute transport in a fluid layer in presence of double-diffusive thermal convection is discussed. It is shown that the variatio…
