Multiscale Modeling of Multiphase Flows

Research output: Chapter in Book/Report/Conference proceedingChapterAcademicpeer-review


Multiphase flows are frequently encountered in both nature and large-scale industrial processes. The inherent multiscale nature of multiphase flows and associated scientific challenges, makes numerical modelling of multiphase flows very complex. In this chapter we will focus on the modelling of gas-liquid, liquid-solid and gas-liquid-solid flows. The different simulation techniques are grouped in terms of Euler-Euler, Euler-Lagrange and fully resolved or Direct Numerical Simulation techniques. Both the governing equations and numerical implementation will be presented, as well as different methods to describe the interfaces between phases. Special attention will be given to the exchange of Momentum, Heat and Mass between the phases. Each subsection will contain a short discussion on the application of the different methods presented.
