Abstract:

In this study, free surface and pattern of Flow through a 90° sharp bend, Using FLUENT software, and utilizes both VOF and Mixture models with k  (RNG) turbulence model have been simulated. To verify the numerical models, experimental results conducted in this research is used. The results indicate that both models are well able to predict the flow pattern of the bend. But the VOF models with an 0.03 average error reffer to the Mixture model with 0.125 Average error to better fit with the experimental results
