Good Afternoon,
I am having some trouble calculating what my power density should be in my 2-D model. I am modeling a cross sectional cut of a heated aluminum plate in air. In my experimental runs, the plate has a power of approximately 60 Watts. If I did a 3-D model, the power density would just be 60W divided by the total volume of the plate. But What should I input in a 2-D model. How should this be scaled. I have looked at the previous posts describing this but still am having trouble visualizing it. The total volume of the aluminum plate is 8.8 in^3.
In my current 2D model, I just input 60W/8.8in^3. The simulated model and experimental results are off in temperature (almost by a factor of 2).
Any suggestions would be great.
Thanks,
Lucas
