Best Practice Guidance Seminar CFD for Dispersed Multi-Phase Flows 2019 With Problem Shooting Session

17-18. May 2019, ERCOFTAC PC Brazil, 
Hotel Windsor Barra, Barra da Tijuca, Rio de Janeiro, Brazil (prior to ICMF 2019)

Main lecturers:

Prof. Dr. Berend van Wachem,
Mechanical Process Engineering, Otto-von-Guericke University Magdeburg, Germany

Prof. Dr.-Ing. Martin Sommerfeld,
Multiphase Flow Systems, Otto-von-Guericke University Magdeburg, Germany

Multiphase Flows Rationale:

The simultaneous presence of several different phases in external or internal flows such as gas, liquid and solid is found in daily life, environment and numerous industrial processes. These types of flows are termed multiphase flows, which may exist in different forms depending on the phase distribution, such as separated and dispersed systems. Examples are gas-liquid transportation, crude oil recovery, circulating fluidized beds, sediment transport in rivers, pollutant transport in the atmosphere, cloud formation, fuel injection in engines, bubble column reactors and sprays for food processing, to name only a few. As a result of the interaction between the different phases such flows are rather complicated and very difficult to describe theoretically.

Consequently, the numerical calculation of multiphase flow systems based on CFD methods also comprises a multitude of different numerical methods each applicable to certain types of multiphase flows and resolving different length and time scales of the problem. The present course focusses on numerical simulations of dispersed multiphase flows and the required modelling of particle-scale phenomena. The hierarchy of available numerical techniques for the different scales in multiphase flows (i.e. particle-scale and industrial-scale simulations) is presented. Both the well-known Euler/Euler and Euler/Lagrange approach, suitable for large-scale simulations of industrial processes, are introduced in detail. Required modelling for particle-scale transport phenomena is presented and the use of particle-resolved direct numerical simulations for their development is emphasised. Examples of a number of advanced models are presented and their effects on large-scale processes are highlighted.

This course is rather unique as it is one of few in the community that is specifically designed to deliver, a) best practice guidance and b) the latest trends in CFD for dispersed multi-phase flows and c) many application examples.

The course appeals to researchers and engineers involved in projects requiring CFD for (wall-bounded) turbulent dispersed multi-phase flows with bubbles, drops or particles.

Moreover, delegates are offered the opportunity to present their work via 10 minute presentations (problem-shooting session), thereafter, the lecturers can offer prospective solution.

Focus of Course:

The course is focusing on dispersed multiphase flows and is delivered during two days prior to ICMF2019 in the same Hotel. The course includes the following topics:

  • Characterisation of multiphase flows
  • Numerical methods for multi-phase flow
  • Industrial challenges and needs for the application of CFD to industrial dispersed multiphase flows
  • Forces on particles, droplets and bubbles
  • Modelling elementary processes in dispersed multi-phase flows (non-spherical particles, inter-particle collisions, agglomeration, droplet collisions)
  • Euler/Euler approach with applications
  • Euler/Lagrange method, fundamentals, implementation, coupling and applications
  • Euler/Lagrange method (Coupled CFD/DEM Simulations)
  • Test case calculations, examples of application and summary of available test cases
