000014705 520__ $$2eng$$aIn the present study we present the results of a fully resolved direct numerical simulation (DNS) aimed at evaluating the influence of corner geometry in fully-developed turbulent duct flows by computing cases with increasing corner rounding radius ‫...‬. Doing so, we evaluate the convergence from square duct .. to pipe flow.... We focus on the decay of the secondary flows present in turbulent duct flows and on further characterizing the mechanisms that produce them. The simulations are performed at friction Reynolds numbers...and 360 using the spectral element code Nek5000.
