| Abstract: | The RNG k-ε turbulence model in computational fluid dynamics software FLUENT was used, and 90° bending duct of circular-section was simulated numerically with three-dimensional, by comparing different initial velocity internal flow field of bending duct, the change regulation and influential factors of pressure field and velocity field was found out, and the secondary flow phenomenon was simulated. The results provide a theoretical basis for studying deeply about bending duct in the further. |
