Abstract

This paper compares the flow behaviour inside Y- junction pipe through a CFD based ANSYS Fluent analysis. The study investigates the influence of pipe diameter (0.1 m and 0.2 m) and inlet velocity (0.297 m/s, 0.397 m/s and 0.497 m/s) on the flow dynamics, pressure distribution and velocity profiles. The simulations are performed by solving the steady Navier–Stokes equations for both incompressible, using the finite volume method. The effects of geometric and velocity changes on flow features, including secondary flows, flow separations and pressure drops, are investigated from which significant differences are observed. These are useful results to demonstrate the internal flow feature of Y-junction pipes, and to optimize design of transporting fluid systems.
