Amit Katz Feb 22, 2016 8:26 AM (in response to Lukas Müller)Flow Sim uses the thermal properties in its fluid database for solving the heat transfer equations alongside the NS equations. If you specify to include heat in your project you will need to add some heat source, otherwise everything will be initialized at the ambient temperature and there will be no transfer between the fluids and solids.

Lukas Müller Feb 22, 2016 11:58 AM (in response to Amit Katz)Hi Amit,
thank you for the response.
If I don`t add a heat source, surely there will be no heat transfer. But anyway SolidWorks is able to calculate / estimate the heat transfer coefficient without any heat transfer.
There are some fluid mechanic formulars which include the heat transfer coefficient. It`s something like Nusselt Nr = PrandltNr * ReynoldsNr)^something, but varies with geometry (and are always empiric). I think Solidworks is capable of calculating the heat transfer number with somekind of the above expression?

Re: Simulate heat transfer coefficient
Amit Katz Feb 23, 2016 9:42 AM (in response to Lukas Müller)OK, you're asking about the actual code used to solve the heat transfer. I misunderstood, I apologize.
This page has some Flow Sim white papers, one of them discuss heat transfer. I didn't read it, so I don't know how technical it is, but maybe worth a shot: Fluid Flow Simulation White Papers  SOLIDWORKS
If not, try going into the technical documentation in the software, there are worked examples so they may discuss the solution method in there.
