This paper focuses on the analysis of Y+ value for capturing laminar sub-layer along the length for fully developed turbulent flow through pipe. It is important to capture the build out of a fluid flow and head loss in a pipe at higher Reynolds number. A finite element method (FEM) solver with k-ε turbulence model implemented with the help of ANSYS FLUENT 14.5 to scrutinize the flow of water at varying velocities as a result varying higher Reynolds number in a 3D pipe. This paper demonstrates computational investigation of turbulent flow inside pipes for varying inlet velocity. Reynolds Averaged Navier Stokes Turbulent model; the k-ε model is used for the simulation. The Reynolds number varies based upon the inlet velocity. The material of pipe is not the concern. The fluid used for this purpose is water of density 1000 kg/m3. The results acquired are well in agreement with the results acquired experimentally.
