Hi,
does anyone know an equation/a way to initialize the turbulent thermal diffusivity (alphat)? For example, if I want to initialize its value at the inlet of a pipe with a known velocity. In other words, how to initialize the turbulent thermal diffusivity (alphat)? Is there a straightforward way? Thanks. |

Hi Vitor,
I don't know what application you are running, but fireFoam has a file named alphaSgs (turbulent thermal diffusivity) under directory 0 in smallPoolFire2D tutorial. Maybe it fits your need. Paulo |
