Perturbation technique

  1. Jul 29, 2009 #1

    I have been trying to model the temperature distribution along the length of a fin.

    With a constant 'h', the analytical solution is easy to get. But in my case, near the tip, the value of h changes significantly.

    Is perturbation a good technique to get a analytical solution in such a case ? If not, any other technique is advisable ?

    What is h in this case? Thickness of the fin? specific heat? Is this a biological fin or a man-made fin?

    'h' - heat transfer coefficient

    By fin, I meant an extended surface.
