Direct numerical simulation of fully developed turbulent flow in a straight square duct was performed in order to determine the minimal requirements for self-sustaining turbulence. It was found that turbulence can be maintained for values of the[...]texto impreso

Pinelli, Alfredo ; Uhlmann, Markus ; Sekimoto, Atshushi ; Kawahara, Genta | Cambridge University Press | 2010We have performed direct numerical simulations of turbulent flows in a square duct considering a range of Reynolds numbers spanning from a marginal state up to fully developed turbulent states at low Reynolds numbers. The main motivation stems f[...]texto impreso
The appearance of secondary flow of Prandtl’s second kind is a well-known phenomenon in fully developed turbulent rectangular duct flow. The intensity of the secondary flow is two orders of magnitude smaller than that of the mean streamwise velo[...]texto impreso
Sekimoto, Atshushi ; Kawahara, Genta ; Sekiyama, K. ; Uhlmann, Markus ; Pinelli, Alfredo | American Institute of Physics | 2011Direct numerical simulations of fully developed turbulent flows in a horizontal square duct heated from below are performed at bulk Reynolds numbers Re(b) = 3000 and 4400 (based on duct width H) and bulk Richardson numbers 0
