Hi


I would like to know the relationship between the courant number and time step size.

I am modeling a micro combustor with inner diameter of 5 mm and 50 mm length.the grid size is about 25~50 micrometer and the flow velocity is about 2.2 meter per second.

I want to capture moving flames.i try time step size of 0.01,0.001 and 0.0001 but the solution will diverge soon.Please give me a tip about it.



thank you for your attention
