“…The capillary bed is where the blood exchanges oxygen and nutrients with the body's tissues and collects waste products. The return of blood from the capillaries to the heart is done through the veins [6]. Veins have a thinner vascular wall than the arteries and the ow of blood in them is low.…”

In this paper, the behavior of blood ow through several consecutive and relatively close clogs inside the vessel is investigated by modeling blood vessels. The used clogs are dual-channel and single-channel currents, which are naturally very close. Consecutive clogs with equal intervals and di erent clogs of 30%, 50%, and 70% are considered. The in ow to the clogged area is in the form of a real pulse, the same as the pulse of blood ow in a vein. For this purpose, the Navier-Stokes equations are solved numerically in an unstable state, while the continuity equation in the capillary coordinate system is solved by the numerical method. The distribution of ow velocity and distribution of shear and vertical stresses in the vessel wall in three states of the ow cycle are related to the acute conditions of the cyclic blood ow. The results show that the rate of increase in shear stresses and the rate of decrease in vertical stresses become much more severe upon increasing the rate of clamping. These changes are more severe at distances of 17 mm for two channels and 25 mm for single channels, which have a maximum blood ow rate.
