Chapter 10 - Future Trends in Handling Turbulent Multiphase Flows

Abstract

This chapter explores the probable future trends in handling turbulent multiphase flows. Owing to the complicated mutual interactions and as a consequence of computational fluid dynamics modelling of gas-liquid-solid fluidisation, direct numerical simulation or large eddy simulation for the liquid phase turbulence in combination with interface tracking/capturing approach for bubble flow and Lagrangian simulation for particle flow can provide the necessary means of gaining significant insights into the prevalent physical processes that occur within such flow system. By calculating the turbulent multiphase flows of technical relevance at sufficiently high enough spatial and temporal resolution subject to the availability of computational resources, these models, in principle, can be utilised to generate the appropriate constitutive relationships that are required for the application of the multifluid model for large-scale multiphase flows.
