Dear all,

I want to make a simulation of a fluid (air with h2) in a enclosure region wich have a width of 0.7 mm. I have 2 inlets, air (3 m/s) and h2 (2 m/s), and it is importat the mixture between them. I used the k-epsilon model for the turbulence... Because of the region is very small, I tried to use the "enhanced wall treatment" for the wall, but I didn't have good results... I think because the region is very small, the whole domain is inside the viscosity-affected region, but in my problem is very important the fully-turbulent region...

Somebody know how can I resolve this problem?

Regards
