Numerical modelling of multiple length and time scales in thermal transport processes

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In a wide range of thermal processes and systems, multiple length and time scales are encountered, making it imperative to model the different scales accurately and couple these to simulate the entire system. In forest and building fires, for instance, the transport processes near the source involve much smaller length scales than far from the source, resulting in different mechanisms, behaviour and concerns. Similarly, in materials processing, the transformations in the material occur at micro and nanometer scales, whereas the system is at engineering scale. This paper presents the major considerations that arise and the approaches that may be used to model and couple different scales. Several examples are presented to illustrate different aspects, approaches and results in multiscale modelling.
