The transfer of heat across a composite wall designed for a system involving heat convec- tion process is shown in Figure 3. The inner wall is insulated. The heat generation with 1300 W/m is provided through layer 1. The proposed condition is that the outer wall should be maintained to the room temperature of T4. The thermal conductivity of layer materials are listed below: Q = Determine: Layer 1; Layer 2; Layer 3; Q=1300 W/m insulated 10mm Material 1; Material 2; Material 3; 40mm k = 20 W/mC k= 25 W/mC k3 = 10 W/mC 20 mm Figure 3: Composite wall T4 = 25C i. Sketch finite element model of the composite wall and label all the nodal and element numbers ii. Determine the element conductivity matrix and heat rate vector for each element iii. Obtain the global system of linear equation for this wall iv. Calculate temperature distribution across the wall v. Determine the heat flux of layer 2.
