Numerical Simulation of Pipe Flow with an Obstacle by applying Turbulent Models

Abstract

The flow analysis is made to simulate the turbulent flow in the pipe with an obstacle. The models used are k-ε, k-ω, Spalart-Allmaras and Reynolds. The structured grid is used for the simulation. The velocity vector, the pressure contour, the change of residual along the iteration number and the dynamic head are simulated for the comparison of four example cases. For the analysis, the commercial code is used.
