Abstract

Y-Junction pipes are widely used in industries sector, home systems, automotive and others. In industries, pipe networks widely used to transport fluid and gases such as water, oil, chemical liquid, oxygen and so on. This junction will help the straight pipe to perform or improve the process of transportation such as from one inlet to be two outlets and from two outlets to be one inlet. Each pipe flow systems are different according to their usability and parameter. In this study, the investigations focus on the effect diameter ratio of branch pipe towards the pressure and velocity behaviour that occurs in the Y-junction pipe. CATIA V5 software is used in order to create a design of pipe. As for determining the effect of various diameter ratios for combining flow, simulation upon the pipe model is conducted by using HyperWorks software. In order to observe the behaviour of fluid flow, generate the mesh and apply boundary conditions in AcuSolve for all diameter ratios of the branch pipe. The inflow types used in surface boundary condition are mass flux, velocity, pressure and flow rate. The types of volume boundary condition used in this simulation are water, diesel and ammonia liquid. The results of velocity against pressure shows, the highest value of velocity magnitude and pressure occurs at the 2 inch branch pipe for result simulation of flow rate, velocity and pressure. Then, the result simulation of mass flux condition shows, the highest velocity and pressure occurs at the 1.5 inch and 1 inch pipe branch respectively. Then, the viscosity of the fluid gives the effect towards the fluid flow behaviour in the pipe system. The high viscosity leads to the high flow resistance in the pipe and causes the velocity in this pipe also decrease. At the end of the task, the conclusion is making and several recommendations are suggested to further advance in this field for future study.
