Default Help with UDF - nusselt number
Posts: n/a
Hi, I need to simulate a turbulent flow in a pipe with heat transfer. I've got an experimental equation for Nusselt number as a function of Reynolds number in the pipe. I wish to know if i can impose Nusselt number in the boundary wall using a UDF or another method. Any link where i can get some information about this kind of problems will be great.

Another question is about how to simulate pressure drop in the pipe using Darcy's friction factor, as a Reynolds number function too.

Thanks in advance for any help and information.
