Flow of labeled blood in small cylindrical tubes and glass bead systems.
• The dispersion or smearing out of a bolus of T 1824 injected into the bloodstream continues to be of interest to the physiologist. Considering the curve of distribution of transit times of injected dye through the lesser circulation, how will this curve be distorted by the necessary act of sampling blood from the aortic outflow through a long tube? In a previous paper, experiments were descri...
متن کاملBlood flow in small tubes: quantifying the transition to the non-continuum regime.
In small vessels blood is usually treated as a Newtonian fluid down to diameters of ~200 μm. We investigate the flow of red blood cell (RBC) suspensions driven through small tubes (diameters 10-150 μm) in the range marking the transition from arterioles and venules to the largest capillary vessels. The results of the simulations combined with previous simulations of uniform shear flow and exper...
متن کاملLarge bending deformations of pressurized curved tubes
In this paper, the problem of large pure bending deformations of membrane is considered. The membrane is a sector of torus with a closed cross-section. This membrane is called a curved tube for short. We consider the homogenous, incompressible, isotropic and hyperelastic material. The external load is a constant pressure and bending couples acting at the edges. The equilibrium equations reduce ...
متن کاملPERFORMANCE MODEL AND ANALYSIS OF BLOOD FLOW IN SMALL VESSELS WITH MAGNETIC EFFECTS
In this paper consider a two-fluid model consisting of a core region of suspension of all the erythrocytes (particles) in plasma (fluid) assumed to be a particle-fluid mixture and a peripheral layer of cell-free plasma (Newtonian fluid), has been proposed to represent blood flow in small diameter tubes with effects of magnetic. The analytical results obtained in the proposed model for effective...
متن کاملCellular flow in a small blood vessel
In the smallest capillaries, or in tubes with diameter D 8 μm, flowing red blood cells are well known to organize into single-file trains, with each cell deformed into an approximately static bullet-like shape. Detailed high-fidelity simulations are used to investigate flow in a model blood vessel with diameter slightly larger than this: D=11.3 μm. In this case, the cells deviate from this sing...
