A Mechanical Analogy for Heat Transfer in Surface Films with Transformations

Author : Rahul Basu 1 2

Date of Publication :30th November 2017

Abstract: A model for describing effects of a variable frequency heat source on the surface of a film is developed. The effect of material parameters is analyzed to describe possible attenuation of the thermal fluctuations and sustaining these through coupling with the surrounding matrix. Application to amorphous alloy formation with phase field concepts is described. An analogy with a damped oscillator driven by surface fluctuations gives the relation of non-dimensional parameters like the Stefan, Fourier and Biot numbers to surface heating with convection. Recent discoveries of high-temperature superconductivity in the femtosecond regimes are included. Impurities and stress fields caused by large oxygen atoms and interaction with the phonon field may be responsible for such effects especially in the "crust" of oxide films. Phonon interactions with driven oscillators in the film may be possible and design of suitable materials to give sustained longer duration high-temperature effects is outlined.
