PROBLEM 4.40 K NOWN: Nodal point on boundary between two materials. F IND: Finite-difference equation for steady-state conditions. SCHEMATIC: ASSUMPTIONS: (1) Steady-state conditions, (2) Two-dimensional conduction, (3) Constant roperties, (4) No internal heat generation, (5) Negligible thermal contact resistance at interface. p ANALYSIS: The control volume is defined about nodal point 0 as shown above. The conservation f energy requirement has the form o 6 i123456 i1 qqqqqqq 0 = =+++++= s ince all heat rates are shown as into the CV. Each heat rate can be written using Fourier’s law,
