Sample text

Simply stated fluid elements are moved by centrifugal forces from the inner to the outer part of the bend. These are then transferred along the wall by a rotational movement towards the inside of the bend (Figure la). The sum of these primary and secondary flows given rise to a double helicoidal motion. With steady flows the initial axial velocity profile is skewed along the curve and peak velocity moves towards the outside of the bend. Pulsatility greatly modifies both primary and secondary flows.

The secondary flow (*) and the centerline (**) are identified, (b) Time course of velocities in positions (*) and (**) respectively. The scale of curve (**) is ten times that of curve (*). The boundary layer appears initially involved with primary flow at the beginning of systole and later with secondary flow. The latter seems to be sustained beyond the end of ejection. JET mm [¢ 24] 10 • jet 24 : -0.

When considering successive cross-sections, from the ascending to the transverse aorta, the increasing thickness of the boundary layer at the inner wall progressively moves the instantaneous peak velocity towards the centerline (Talbot [1], Farthing [3], Yearwood [4]). The profile thus modeled in the mid-portion of the arch is skewed towards the inner part of the curvature in early systole but displays during deceleration a clear' hallow' with a peak maximal instantaneous axial velocity located centrally.
