| dc.description.abstract | Turbulent secondary flows are motions in the transverse plane, perpendicular to a main, axial flow. They are encountered in non-circular ducts and, although the velocity is only of the order of 1-3% of the streamwise bulk velocity, can still affect the characteristics of the mean flow and the turbulent structure. In this work the focus is on secondary flow in semicircular ducts. Both numerical and experimental analyses are reported. It is found that the secondary flow in semi-circular ducts consists of two pairs of counter rotating corner vortices, with a velocity in the range reported previously for related configurations. Agreement between simulation and experimental results are good when using a second moment closure turbulence model. | en_ZA |
