摘要：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.
