Concepts:

• 2D Modeling/Simulation
• Steady State Heat Transfer
• Conduction and Convection

  The figure shows a 2D section of a composite wall subject to a steady-state heat transfer condition.  (All dimensions are in meters).

There are six materials in this construction (A, B, C, D, E, and F).

k_A = 2, k_B = 8, k_C = 20, k_D = 15, k_E = 35, and k_F = 2 W/m-^oC

Each section is in perfect contact with adjacent sections (no contact resistance).

The top and bottom edges are adiabatic.

On the left side, T₁ = 350^oC and h₁ = 145 W/m²-^oC

On the right side, T₂ = 50^oC and h₂ = 95 W/m²-^oC

Turn in:

• a geometry plot showing multiple bodies for this structure
• an Environment plot showing ALL loads and boundary conditions 
• a final results contour plot of the temperature distribution in the part
• report the mesh error % (TEPC) for your model
• the ANSYS reaction solution (heat flow at each convection face) compared to a hand calculation of the total heat flow
• hand calculation of the temperature at point “X” (which is the point where the corners of sections D and E meet section B), compared to the ANSYS contour results plot.
