Hi all...

I am trying to simulate a flow in a ribbed channel

periodic boundary conditions are to be used

i have tried various meshing techniques including the size functions etc but still I am getting very high heat transfer values compared to experiments.

i am using k-eps standard EWT, with energy equation (k-w model apparently doesnt give desired velocity profiles)

if I make the cells too close to the wall, I get an error in fluent that "Aspect ratio is very high for some cells and the default code might not work".

The link to the problem description is (

Please reply ASAP
