ASSIGNMENT 2- due Feb 27 Cross-section 1 Fin 3-D View of the System h=0 Top view h=btop h=hp Wo k=k k=k r h=hot Ty Streaming fluid T h=hbet T, = 85C, T, = 15C, hop = 20W/(mC), hot = 35W/(mC), k =25W/(m C), k = 50W/(mC) Wo 3 cm, r = 2.5 cm, r = 4 cm, r = 7 cm = Consider both a perfect interface and an imperfect interface. For a perfect interface: continuous temperature and conservation of energy yield: 7(x,y,z)=7(x,y,z.1) For two fins whose cross-sections are shown calculate the temperature and the heat flux at any cross-section. Run the program for a) a = 0 and b) = 12 Find the temperature at the cross-section where the fin changes shape. Plot the temperature as a function of r in rr r3. For a = 0 compare the numerical results against the analytical solution k =k ax For an imperfect interface: jump condition on temperature using contact resistance and conservation of energy yield: h(T-T)=-k Ox 07, k ax Consider h=1500 W/(mK).
