Modeled our Capstone project- time to heat a Zirconium Billet to 140-145 degrees
farenheit
Used 1
st Term ApproximationCompared to experimental measurements
OverviewSlide3
First we assumed an infinite cylinder, in order to neglect end effects.
Solved for the h value
h=405
Found the Biot number to be too high for lumped capacitance (lumped capacitance method gave t=35.75 seconds)Used 1st term approximation to solve for time
Found t to be 84
seconds, with Fo=.442787
Finding the ValuesSlide4
Found time to heat to be 84 seconds
50 seconds was the measured experimental time
Accuracy was 68%
ResultsSlide5
Compare these results with Concentric Cylinders values (another group project)
Determine end effects ( )
Examine changes in start temperature of billet (i.e. changes in seasonal temperatures- winter to summer)
Conclusions
