Abstract:A new model on the heat transfer processes in nanostructures considering that heat flow paths take place on fractal curves is established. In the dissipative approximation of this process, for Peano type heat flow paths and synchronous movements at differentiable and non-differentiable scales, the heat transfer mechanism is of diffusive type. In the dispersive approximation of the same process, both at differentiable and non-differentiable scales, the thermal transfer mechanism is given through the cnoidal oscillation modes of the temperature field (ballistic thermal transport). In such conjecture, two flow regimes result: one by means of waves and wave packets and the other by means of solitons and soliton packets. Practically, we discuss about an unique mechanism of thermal transfer in which the usual one can be seen as approximations of it.
