Direct numerical simulation of thermal channel flow for and

A direct numerical simulation of turbulent heat transfer in a channel flow has been conducted for a Reynolds number of is increased. Finally, the turbulent budgets are presented. A relation between the increment of the inner peak of the temperature intensities and the scaling failure of the dissipation and viscous diffusion terms is provided. The statistics of all simulations can be downloaded from the web page of our group: http://personales.upv.es/serhocal/.
