For a perfect interface: continuous temperature and conservation of energy yield: T(x,y,z,t)=2(x, y, z,t) For two fins whose cross-sections are shown calculate the temperature and the heat flux at any cross-section. Run the program for 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 r, Srr. For a 0 compare the numerical results against the analytical solution T k Ox T Ox For an imperfect interface: jump condition on temperature using contact resistance and conservation of energy yield: h (T-T)=-k Ox k , =k ax x Consider h.-1500 W/(mK).
