Abstract

Pipes are key components in maintaining a progressive pipe system in industries since they serve as a medium for fluid or gas passage from one place to another. When a flowing fluid travels through a bend or turn in a pipe, it causes a flow inside the pipe known as "secondary flow," which results in a stress distribution inside the bend. Because the pipe bend portion is fixed at both ends, this stress causes the pipe to deform; if the deformation forces are significant enough, the pipe can break. Even if the imposed load does not immediately create a rupture, vibrations inside the flow may occur. More serious risks, including as explosions, will arise if the situation is not appropriately controlled and resolved. The major goal of this research is to analyse the influence of pressure and velocity on pipe deformation at 90° and 45° bending, as well as the effect of a flow separator on pipe deformation at 90° and 45° bending. One of the key reasons we selected this bending pipe specification is the relationship between flow and structure. An ANSYS software simulation is a tool for determining the permissible flow through a pipe. This tool will aid in the resolution of piping system difficulties caused by flow vibration and fluid solid interation between the flow and the pipe structure. Furthermore, performing this simulation first will save money and time. As a result, it will depict the fluid movement and heat transfer that is possible in pipe modelling. We will learn about the influence of velocity and pressure on the pipes in this project.
