Some hints for modeling the data - 1. For the transients, you assume in the model that for time>0 you have the end of the rod at Tsteam. Your modeling will not work if you have data that is before the steam is turned on. Your modeling will also not work if you have data at time=0; use time=.1 or something greater than zero for the first data point. 2. Do a purely theoretical fit to the transient data. You have a heat transfer coef from the steady state - see how well the equation fits to the data. Why does it miss? By tweaking which parameters can you get better fits? What does this say about your model and assumptions?

Unformatted text preview: 3. You may not have time to fit transient data for every rod and every thermocouple. Select some smaller set of thermocouples for 2-3rods and see how the model fits. One thing to definitely allow to vary as you play with the modeling is Tsteam. 4. Memo - should go over some of the salient findings - what can you say about aluminum vs stainless steel? How does the rod diameter effect the temperature profile? How well does the model work for steady state? For transient? What sort of heat transfer coef do you find from your data? How does your experimental heat transfer coef compare to theoretical values?...
