Hi everyone!

How are you all doing?

Apologies but I was unable to find a dedicated SolidWorks Forum on the website.

I am working on a thermal model in SW Flow Simulation. I noticed a discrepancy in the value of the convective heat transfer coefficient ('h') obtained directly from the simulation (i.e. by using a surface goal) vs. calculating it via an equation goal using Newton's law of cooling, and I am unable to get to the bottom of this.

To verify which of these values are correct, I calculated the heat generated in the model (with an equation goal) using the 'h' obtained directly from the simulation (i.e. by using a surface goal) and compared it to the known value of heat generation which was inputted in to the model, and the two values differ greatly.

The flow is turbulent, forced, and the heat convects from a heat generation source directly onto the fluid.

Kindly help.

Thanks !

below is the dedicated solidworks flow simulation forum (SWFS is actually a FloEFD code)

Thanks! I'll ask there
