convergence for coal combustion

June 30, 2006, 03:44

Hallo,

my name is Benjamin. For my final thesis I do a coal combustion simulation. To get familiar with the subject I calculate a simple combustion process without radiation. The 2d calculation has converged, but the 3d model has not yet. I have tried diferent physical timesteps but nothing has led to a convincing result. Has anyone a suggestion for me?

Thanks in advance.

Read the "Advice on flow modelling" and "Near wall meshing (?)" sections in the modelling chapter of the CFX manual.
