Abstract—In this study, CFD analysis of the vertical tube is conducted. A vertical copper tube having constant cross section area is used for representing the medium through which natural convection of water takes place. In this present work the study and analysis of natural convection flow of water through vertical pipe is done. In this study includes what is the effect of the physical parameters of tube like diameter, length and heat flux on the outlet flow parameters like velocity and temperature. Constant heat flux is boundary condition is provided on the entire tube surface. In this study we found that outlet temperature outlet velocity that is going to be increased as tube length is increased but as diameter of pipe is increased outlet temperature is increased but velocity is decreased. In this thesis GAMBIT is used for creating geometry and specifying boundary conditions as well as FLUENT software is used as solver and giving boundary condition. Finally CFD results and experimental results are compared which validate the software results.
