Abstract
Mass transport and diffusion phenomena in the arterial lumen are studied through a mathematical
model. Blood flow is described by the unsteady Navier -Stokes equation and solute dynamics by an
advection-diffusion equation, the convective field being provided by the fluid velocity. A linearization
procedure over the steady state solution is carried out and an asymptotic analysis is used to study the
effect of a small curvature with respect to the straight tube.
Analytical and numerical solutions are found: the results show the characteristics of the long wave
propagation and the role played by the geometry on the solute distribution and demonstrate the strong
influence of curvature induced by the fluid dynamics.
