Cite This Study

Ling et al. (1973) studied this question. Nonlinear analysis of aortic flow was evaluated on Velocity profiles, wall friction, and discharge waves. A nonlinear theory accounting for convective accelerations correctly predicted velocity distributions and flow waves in the descending thoracic aorta of living dogs.
