摘要：
The unsteady flow of blood in a straight, long, rigid pipe, driven by an oscillatory pressure gradient is studied. Three different non-newtonian models for blood are considered and compared. One of them turns out to offer the best fit of experimental data, when the rheological parameters ale suitably fixed. Numerical results are obtained by a spectral collocation method in space and the implicit trapezoidal finite difference method in time. (C) 1998 Elsevier Science Ltd. All rights reserved.
