Wall shear stresses are thought to have an influence on the formation of deposits of
blood fats on the linings of the arteries, in atherosclerosis. Measuring velocities
close to an artery wall to determine wall shears is difficult in view of the thinness of
the boundary layer. Analytical solutions are limited to simple geometries and
numerical analyses of three-dimensional, unsteady blood flows are expensive in
terms of computational time. In the present study, finite element analyses of blood
flow in models representative of the human aorta are based on two-dimensional
sections in order to reduce the computational requirement. [Continues.]
