Objective Due to the great importance of two-phase flows in technical and industrial processes numerical methods are required to support the design and optimization of such processes: cyclone separators, fluidized beds, spray painting, or spray/coal combustion. This project aims to develop and improve numerical methods for dispersed two-phase flows with heat and mass transfer by using three different approaches for the dispersed phase, namely the Lagrangian, the probability density function, and the Eulerian approaches. All three methods require a certain degree of modelling which will be a major task in the project. Many of the micro-physical effects governing a two-phase flow can only be considered by empirical or semi-empirical numerical models and hence require detailed experiments and theoretical studies for their derivation. To facilitate such developments experimental and theoretical investigations on the following physical effects will be performed during the project: particle turbulence interaction, turbulence modulation by particles, particle-wall and droplet-wall interactions, particle-particle and droplet-droplet interactions, particle/droplet evaporation and combustion. Appropriate numerical models will be derived and incorporated into the three different numerical approaches for the dispersed phase. The numerical methods and models developed will be validated using existing experimental results or data which are obtained by the participants during the project. A comparison of the numerical results obtained by the different numerical approaches for the dispersed phase will demonstrate their relative capabilities. Test cases to be considered are: particle-laden swirling flow, particle-laden horizontal channel flow, spray evaporation in a turbulent heated air flow, interacting sprays, and spray and coal combustion systems. Joint workshops will be organised to discuss the numerical results and the advancement of the project.
