Heat transfer from a fluid to a solid

  1. Oct 23, 2007 #1
    I need a hand understanding the behaviour of a system which follows:

    Hot combustion gases emerge from an aperture at a fixed temperature and pressure and pass through a length of tube.
    How does the diameter of the aperture and tube, plugged into bernoulli's principle, turbulence of the gas, surface area of the inside of the tube, length of tube, heat capacity and conductivity all effect how much heat is transferred to it.

    Heat in the combustion gases are to be considered lost if they emerge from the end of the tube, and only useful if the heat radiates from the surface of the tube according to Stefan's law (emissivity constant 0.8 lets say), and that being a real world situation, the tube has to fit into a fixed volume, and that too much resistance to flow would probably not be good for the heat source ... what is the best configuration for the tube?
