Abstract

Based on the commercial software ANSYS CFX the computer simulation of heat transfer and hydrodynamics was performed in the round tube with incline-tangential flow swirl at the inlet and flow 90° turn at the exit. Two groups of turbulence models and basic parameters of the computer grid were verified allowing obtain the accepted accuracy. Comparison of predicted and experimental results showed that k-ω turbulence model provides good agreement for the surface swirl angle, all tested models describes well the pressure drop coefficient, while LRR model of Reynolds stresses predicts precisely heat transfer data.
