I have made a wind tunnel; wall is 60 celsius and the air is 25 degree. But the wall heat transfer coefficient is a fluctuating diagram. I've checked everything.
does anybody know why is happens? |

Have you tried these tips?
http://www.cfd-online.com/Wiki/Ansys...gence_criteria What do you mean by "But the wall heat transfer coefficient is a fluctuating diagram"? Are you running steady state or transient? How are you monitoring wall heat transfer coefficient? |
