Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.
Large-eddy simulation is applied to simulate the mixing of
the hot and cold fluids in a T-junction packed with periodic
array of sintered cooper spheres based on the fluid-solid
coupling method. The numerical results reveal that the thermal
striping phenomenon is obvious and the temperature and
velocity fluctuations are weakened in porous media region.
Compared the results of cases with the same physical models
and velocity conditions, the increasing temperature difference
between the main inlet and the branch inlet does not impact on
the hot and cold fluid flow and heat transfer obviously due to
change the hot and cold fluid duct in T-junctions.
