Factors affecting heat exchange

  1. Sep 22, 2009 #1
    Heat transfer is something I've been interested in since studying thermodynamics last semester, although during the course we never really covered anything much to do with what affected heat transfer. I can pretty easily understand that obviously having a higher surface area to exchange across, temperature differentials and the time to which it is exposed will all affect the rate of transfer - but what else is there [if anything]?

    Does what the material consists of or the shape of the material [other than to maximise contact with the thermal body] affect it?

    Thanks for any insight =)

    You can divide the variables into three areas: the material properties, the material geometry, and the driving force (the temperature difference). Sure, the material's thermal conductivity, density, specific heat capacity, and geometry, among others, could all play a part in the results.

    is there anything you'd recommend for me to read to find out about all the known factors that affect heat transferance?

    and thanks for your reply =)

    Take a look at Incropera and DeWitt's Fundamentals of Heat and Mass Transfer. It's a textbook that's clear and useful enough to also serve as a handbook.

    Thanks Mapes, i'll look into it!
