The Main Objective Of Providing This CFD Simulation of Two Phase Flow in Horizontal Pipes fin al year Chemical Engineering M Tech Project is to give basic abstract and introduction to all M Tech final Year graduates for their project selection. The main advantage of this system is to predict the transition of Two Phase Flow Regime in horizontal pipe with the help of FLUENT using the VOF Model. We have successfully developed this project in Master of Technology and results have helped understand type of flow regime especially in equipment’s like boilers and in transportation of oil and gases in pipelines. Findings are especially important due to the complexity of two-phase flow.
