Solidification at the nanoscale

2018 edition

Marc Calvo Schwarzwälder

Nanoscale solidification is becoming increasingly relevant in applications involving ultra-fast freezing processes and nanotechnology. However, thermal transport on the nanoscale is driven by infrequent collisions between thermal energy carriers and is not well described by the classical Fourier law. In this study, the role of non-Fourier heat conduction is studied by coupling the Stefan condition to the Guyer-Krumhansl equation, which is an extension of Fourier’s law that includes memory and non-local effects. The results from this study provide key qualitative insights that can be used to control nanoscale solidification processes.
