Daft heat transfer nomenclature question

  1. Apr 14, 2008 #1
    Heres's my question: is the "diffusion" part of convection (which I understand to be advection + diffusion) equivalent to simple conduction? This is of course assuming an incompressible fluid such that no natural convection is possible.

    I hope this is clear and to the point enough, but please ask if it needs clarification.

    Yes; in the context of heat transfer, "conduction" is equivalent to thermal energy diffusion.

    Well there is also molecular diffusion (say a flame) superimposed on the heat diffusion whenever the medium is non homogeneous.
    To be quite honest I don't really understand your question.
