Numerical analysis of turbulent flow in 90 degree square sectioned bend
Abstract :
In this study, steady, incompressible, viscos and 3-D turbulent flow in a 90° square section bend numerical investigation has been aimed. Square section bend examined on experimental studies have been done in the literature [10, 12 ve 14], which has 80x80 mm^2 section, 160 mm curvature radius, 2500 mm upstream and 1500 mm downstream. RNG (renormalization group) k-epsilon, SST (shear-stress transport) k-omega and RSM (Reynolds stress model) models are selected. Numerical analysis was carried out for Re=40000 air flow. As a result, it is seen that the most acceptable model for numerical analysis of turbulent flow in bend is RNG k-epsilon turbulence model.
