ABSTRACT

This article discusses multiphase flow as one of a general class of "complex" systems which occur in nature. A system is defined as complex when its behaviour cannot be explained (and predicted) based on an understanding of its component parts. The concept is illustrated by considering examples including boiling, droplet breakup and mixing processes between a hot molten material and a hot fluid. Methods of addressing such complex systems using multi-scale computational models are discussed.
