Hi Dears
I found this quota in a paper, why implementation of constant heat flux is difficult? "For the thermal boundary condition, the temperature distribution along the pipe wall was specified, based on the data. Although a constant heat flux was applied as the thermal boundary condition in the experiment, with the present DNS technique it is didifficult to treat a constant wall heat flux condition for spatially developing flow problems" Thanks for your time |

From this statement is not clear .... as DNS is referred as, the number of grid point in the thermal BL have to be sufficient to impose a Neuman BC. |
