Abstract
A “Finite Element” method is developed for carrying out the direct numerical analysis of viscous hemodynamic flow in a long tube, under arbitrarily time-varying end pressures. The method yields directly the velocity and shearing stress profiles at the vessel walls. Results are checked with known profiles obtained by Womersley for sinusoidal input, and applied to experimental data furnished by Fry and Greenfield on measured aortic pressure gradients.
