ENGR 467 - Heat Transfer

Project # 2 Due...................

Use the finite element software FEHT to show the temperature distribution in the walls of a two dimensional furnace shown below. The furnace is at 750 F and the convective heat transfer coefficient inside and outside of the furnace are 40 and 10 Btu/ft².F.hr respectively. Calculate the amount of heat lost to the ambient and determine the maximum and minimum temperatures in the metal and the insulation?

To evaluate the warm-up time of the furnace, assume it is initially at ambient temperature and suddenly exposed to 750 F gas. Approximately how long it will take to reach steady state?

Submit your results along with tech memo and a rough hand calculation to confirm the finite element results.

Furnace internal dimensions: 2' x 4'

Furnace walls: Stainless Steel, 1" thick

Insulation: Calcium Silicate, 4" thick
