✦ Synopsis

Steady state •aminar •uid •ow thr•ugh d•ub1• vascular c•nstricti•ns was studied numerica1•y. A false transient m•d••

was proposed and used with a mesh transformation technique for the modelled double vascular constrictions. The numerical model was used to study the streamlines, velocity and vorticity distributions as the flow passes through double constrictions in a vascular tube. For double vascular constrictions of spacing ratio S/D = 1, 2, 3 and cc with a 50% diameter constriction, a Reynolds number range of 5 to 200 was studied. Comparisons were also made with the available data from other investigators.
