| Abstract: | The paper is concerned with numerical simulations of the 3D Newtonian flows in cylindrical capillary bifurcations up to Re = 100. There are studied two types of branching geometries: (i) a “T” symmetric bifurcation and (ii) a “L” bifurcation, respectively. We investigate the Reynolds number influence on the flow field, vortical structures and secondary flows, in vicinity of the junction between the capillaries tubes. The numerical simulations prove the capability of CFD not only to model qualitatively the flow in bifurcation and branches, but also to compute values of interest and relevance for practical applications. Biofluid dynamics is a “target” of the present work, in particular our interest is to provide a procedure to compute the shear stresses at the wall of the blood vessels. |
