Numerical simulation of turbulent flow through a square-sectioned duct with a 90-degree bend using FLUENT

The turbulent flow in a square-sectioned duct with an installed bend was investigated numerically. The calculations were based on two different turbulence models, namely the standard k-epsilon model and the k-omega SST model. The numerical computations were carried out using the commercial software package FLUENT 6.1. Numerical results for velocity, turbulent intensity and pressure distributions are presented. The obtained results of numerical calculations are compared with corresponding results of experimental studies available in references. The comparative analysis of the obtained numerical results and experimental ones, proved a high degree of their consistency.
