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?
Assumptions: • The billet shape is symmetrical. • EGC Enterprises Q Foil Heaters were used as the heating elements. • Heaters Produce q’’ = 100 W/in^2 • (q_dot = 2.44x10^8 W/m^3) • 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 – 1in^2 heaters needed.
