The Problem

• Find all nodal temperatures during the heating of
  a aluminum wing billet.
• How many heating elements are needed to obtain
  450 K at the center of wing billet?

4
Assumptions

• The billet shape is symmetrical.
• EGC Enterprises Q Foil Heaters were used as the
  heating elements.
• Heaters Produce q 100 W/in2
  
• (q_dot 2.44x108 W/m3)
• Forced air convection
• Heaters only cover the top and bottom of wing
  billet.

Conclusions

• All nodal temperatures were found.
• 450 K was obtained at the center
  of wing billet.
• 2880 1in2 heaters needed.
