Abstract

The authors derive the equation for the velocity vector in the axial direction for an incompressible, Newtonian fluid, flowing through a nonuniform, symmetric, rigid, cylindrical tube. The authors apply their solution to regions of arteriosclerotic plaque in mammalian arteries and state the conditions under which their assumptions are valid. The results of simulations carried out for several shapes and sizes of plaque deposits, which have been modeled by a β-distribution, are presented
