Present paper presents some experimental and numerical modeling of Newtonian and viscoelastic flows in bifurcated configurations, for stationary and non-permanent regimes. The experimental measurements was performed into a closed circuit of pipes, with different diameters, consisting mainly into a centrifugal pump, a supplying tank, sensors for estimating the pressure losses and apparatus for flow rate estimation, presented detailed into a dedicated paragraph. The main pipe is direct connected to a transparent bifurcation at different angles from the main pipe axis. The experimental measurements illustrate that the flow has different aspects, depending of the angle of the bifurcation. The numerical simulations are performed with Fluent CFD based on the volume numerical technique, as to obtain the Navier-Stokes solutions for the Newtonian model in the laminar or turbulent flow conditions. A pre-processor has been used to create the geometry of the bifurcation and to generate the mesh. The 3D-flow domain contains 944390 volumes, tetrahedral/hybrid. It was explored the numerical solutions of the fluid flow in branching pipes for Re numbers from 1000 up to 40000. The governing equations were assumed from the k-e model for turbulence flow: equation of continuity, equation of fluid motion, and the transport equation. The main purpose of the paper was to determine an optimal pipes bifurcation as to minimize the local losses and.

Finally some discussions, remarks, conclusions and references are mentioned

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
