Mass Transfer Cooling Parts in Pressure Furnace
(OP)
I am having difficulty determining the cooling rate of the following application:
600 lbs of 1/4" x 4" steel pins (approx 7100 pins)
Cooling medium: Nitrogen at 15 psig
Gas recirculation at 5000 CFM
Initial load (pins) temp: 2000 deg F
Gas temp into load area: 150 deg F
The first issue I have is determining the final gas temperature as it leaves the load area to go into a heat exchanger. From this I will then need to size the heat-exchanger needed.
Can anyone recommend a solution to this problem.
Thank you

If they are random, its eems like a numerical solution for this would be a real bi*&$ to develop. Somewhat easier for uniform orientation. I suppose one of the higher-end CFD packages could deal with it, but it is a non-steatdy state problem. I'm not convinced that the CFD boys are quite there yet for transient analysis.
In either case, I'd think it would be much easier to do a few small-scale tests
