Multi-phase 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. 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 spray 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 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 approaches for
particle-scale transport phenomena are presented and the use
of fully resolved direct numerical simulations for their
development is emphasised.

This course is rather unique as it is one of few in the
community that is specifically designed to deliver, a) 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. Registration is required: martin.sommerfeld@ovgu.de.
