Abstract

This research is about the study of the effects of branch pipe diameter ratio of fluid flow for Y-junction pipe for dividing flow. One of the simplest devices use for this purpose is the Y-junction connected with the main channel and branch pipe. The understanding of fluid properties likes velocity, pressure loss and viscosity is the main study in this project due to different diameter of branch pipes. In order to achieve the objective of the study, the Y-junction pipe models are designed using Catia software. After that, the pipe models are simulated in AcuSolve of HyperWorks software. In order to observe the behaviour of fluid flow, generate mesh and apply boundary conditions has been done in AcuSolve for all different diameter ratios of branch pipes. One of the main findings is the highest pressure loss occurs at the 26.6 mm which is the smallest diameter of branch pipe among other two different branch pipes. The pressure losses will decreases when the diameter ratio of branch pipe increases for all inlet conditions. Besides that, the velocity shocks occur at the edge of junction pipes for all branch pipe diameters. This is due to change of pipe direction (junction) during the flow of fluid. It also observed that the higher the diameter ratio of branch pipe, the velocity magnitude at branch outlet will decrease. Then, viscosity of liquids are the main factor that affect the the pressure and velocity during fluid flow in pipe. At the end of the task, the conclusion is making and several recommendations are suggested to advance this field further for future study.
