Modeling And Simulation Of Multicomponent Flows.

Abstract

Before describing what this paper really is, a few words on what it is not. The following
description of the main characteristics of multicomponent flows and of some of the models
used for their solution is not to be taken as a comprehensive and complete review, provided
such a thing were possible in an field as complex and rich in models and variations as the
present one. This is only a very brief bird’s eye view of a very complex research field. Some of
the references given are just to be taken as examples, not as best or first papers in each
subject.
This is a brief introduction to the field of multicomponent flows for people with numerical
experience and knowledge of single phase CFD modeling. The most renowned models
available in the open literature are classified into four categories, namely Averaging, Surface
Tracking, Entity Tracking, and Meso/Microscopic models. The models are briefly described,
using not equations, but words and images. The readers are encouraged to consult the
references for mathematical and numerical details. Comments on computer power
requirements, range of applicability, complexity, etc., are also included in the description of
some of the methods.
