Velocity Effect Investigation on the Flow Parameters in Y-Duct

Mechanical Engineering

2nd National Conference on Recent Trends & Innovations in Mechanical Engineering

The influence of velocity on the flow parameters had been investigated in this present work. The small junction of pipe network i.e. Y branch has been concentrated in the present investigation. The mesh tool (Altair Hypermesh 16.0) had been used to model the geometry and to mesh the same. Ansys 16.0 i.e. Fluent CFD analysis tool was used to carry out the simulation part of existing problem of the fluid flow through Y-duct having 45º branching angle. The results are evaluated by varying the inlet boundary conditions i.e. for different velocities. Through this investigation it has observed that, as the fluid passes through the branch, there exist a drop in pressure and uneven flow distribution at the junction. The inequality in mass flow distribution and loss in pressure are the function of turbulence and velocity. Also, it has observed that the pressure distribution at the two outlets is uniform for lower rate of velocities. The less turbulence occurrence at 45º branching, results into unvarying pressure distribution at the outlets. Further, the mass flow distribution at the branching zone is found to be uniform for the lower rate of velocities. This equality in rationing of flowing fluid is due to less angle segment and low turbulence occurrence at the distributing region. Thus, typically it can be wrap up that the loss in pressure, pressure distribution and mass flow distribution will be influenced by velocity parameter of flowing fluid
