WebEnergy Transfer on the Ground Potential Energy Surface: Large and Medium Size Molecule Dynamics Historical Perspective. Ultimately, interest in the mecha-nisms by which molecules lose or transfer energy during collisions is driven by the effect such events have on the potential chemical reactivity of the individual molecular species. WebConvective heat transfer occurs as a result of the transfer of energy between a moving gas or liquid phase and a solid phase. Typical examples include the energy transfer which occurs in process heat exchangers or in air cooled exchangers. Here, the mechanisms can be divided into natural convection and forced convection processes.
