CFD for Dispersed Multi-Phase Flows

CFD for Dispersed Multi-Phase Flows

Venue: La Sala Strozzi, Univ of Florence, Rettorato, Piazza San Marco, 4 - Florence, Italy
Date: 16th of October 2009


The simultaneous presence of several differentphases in external or internal flows such as gas, liquid and solid isfound in daily life, environment and numerous industrial processes.These types of flows are termed multiphase flows, which may exist indifferent forms depending on the phase distribution.  Examples aregas-liquid transportation, crude oil recovery, circulating fluidizedbeds, sediment transport in rivers, pollutant transport in theatmosphere, cloud formation, fuel injection in engines, bubble columnreactors and spray driers for food processing, to name only a few. As aresult of the interaction between the different phases such flows arerather complicated and very difficult to describe theoretically. Forthe design and optimisation of such multiphase systems a detailedunderstanding of the interfacial transport phenomena is essential. Forsingle-phase flows Computational Fluid Dynamics (CFD) has already along history and it is nowadays standard in the development ofair-planes and cars using different commercially available CFD-tools.

Due to the complex physics involved in multiphaseflow the application of CFD in this area is rather young. Theseguidelines give a survey of the different methods being used for thenumerical calculation of turbulent dispersed multiphase flows. The BestPractice Guideline (BPG) on Computational Dispersed Multiphase Flows isa follow-up of the previous ERCOFTAC BPG for Industrial CFD and shouldbe used in combination with it. The potential users are researchers andengineers involved in projects requiring CFD of (wall-bounded)turbulent dispersed multiphase flows with bubbles, drops or particles.
