HTC

Karol

Hi!

I'm new here. My name is Karol and I'm a student of Warsaw University of Technology (Poland). I've read a discussion about using commercial codes at school and yes, I'm using Fluent in my Thesis. Maybe it's wrong but I've already learned a lot and my value to the potential employer is bigger, I hope. In my country it's hard to get a job and companies look for employees already prepared to work, with knowledge of commercial codes they use.

I have problem with Heat Transfer Coefficients I got. HTC are half of what I expect to be. My question is: How is HTC calculated in Fluent?

My second concern is: How to set roughness in Two-Layer Zonal Model? When I used standard wall functions I could set roughness in boundary conditions/wall window, when I switched to Two-Layer that option disappeared.
