Abstract

The flow and wall shear stress in a 90° T-bifurcation model is analyzed numerically. The nonlinear Navier-Stokes equations for incompressible Newtonian fluid flow are approximated using finite volume method approximation. The wall shear stress is calculated from the velocity field. The investigation shows viscous flow phenomena such as flow separation and stagnation and the distribution of high and low wall shear stress during flow through the tube. Furthermore, the effect of a sharp corner at the bifurcation edge on the wall shear stress is analyzed.
