Abstract:

A new methodology for resolve complex problems in fluid mechanics has been known as computational fluid dynamics (CFD). CFD investigates parameters such as velocity field, pressure, shear stresses, effect of turbulence and etc in flow field. In this paper, a three-dimensional CFD model was used to investigate of flow patterns, velocity profiles and also accuracy of numerical models in 1phase and 2 phases was investigated. For numerical simulation ANSYS-CFX software was used. The k-? turbulence model was used to solve turbulence equations. The results showed that secondary flow and centrifugal force influenced flow pattern and have good agreement with experimental
