A. Murata et S. Mochizuki, Large eddy simulation of turbulent heat transfer in an orthogonally rotating square duct with angled rib turbulators, J HEAT TRAN, 123(5), 2001, pp. 858-867
Heat transfer in a rotating rib-roughened duct was simulated with a Lagrang
ian dynamic subgrid-scale model The angled 60 deg rib induced a pair of str
ong vortices in the stationary condition, and the heat transfer and the fri
ction factor were larger them the 90 deg rib case. In the rotating conditio
n, the high heat transfer areas at the midpoint between ribs and in front o
f the rib were observed only on the trailing wall. The friction factor and
overall Nusselt number were decreased by the duct rotation for 60 deg rib c
ase, although they were increased for 90 deg rib case.
