Fin effectiveness vs fin efficiency for applications

  1. Feb 20, 2014 #1
    So we've been doing fins in class.

    I understand that the formulas for fin effectiveness and efficiency are similar, except the area used in the denominator (Ac i.e. area of cross-section for effectiveness and As i.e. surface area for efficiency).

    However, my question is while designing a fin, which of these parameters is the more important to consider?, from a practical perspective.

    Thanks,
    Urmi

    What is the subject of this post?
    Fins used for stability in fluid flow?
    Or maybe fins used in heat exchangers?
    Can you provide a link to a relevant page?

    Yeah I mean fins in heat transfer, like you use in electronic devices: http://en.wikipedia.org/wiki/Fin_(extended_surface [Broken])
