| Description: |
Aims of the Summerschool
The atomisation of liquids into small droplets and the
resulting spray
evolution is of great importance for a number of technical
and
industrial processes, as for example: spray combustion,
spray
coating, spray cooling, spray agglomeration, spray
compaction and
so on. Essential for producing a desired spray droplet size
distribution is the atomisation of the liquid using
different types of
nozzles. The spray evolution is mainly governed by the
nozzle
geometry (initial condition) and aerodynamic transport. For
analysing,
optimising and designing spray processes increasingly
numerical
computations (CFD) are being used, also by industry.
Industrial
relevant processes are generally calculated based on the
Reynoldsaveraged
conservation equations in connection with an appropriate
turbulence model. For calculating two-phase flows extended
approaches have to be used. The most known methods are the
twofluid
(or Euler/Euler) approach and the Euler/Lagrange method. In
the two-fluid approach to interpenetrating and interacting
continua
are considered resulting in two sets of conservation
equations with
similar structure, supplemented by the interaction terms.
Multiple sets
of conservation equations have to be used for resolving a
spectrum of
droplet sizes which is especially important for spray
predictions.
The Euler/Lagrange method simulates the dispersed phase by
tracking a large number of computational droplets. This
approach is
very attractive for predicting spray dispersion, however
needs as an
input the initial droplet size distribution. Both methods
need to be
extended appropriately for modelling all relevant elementary
processes, such as liquid sheet or jet break-up, droplet
interaction
and collisions, droplet break-up and heat at mass transfer.
During the 4-day summerschool recent advances on the
modelling
and numerical prediction of sprays will be introduced. The
areas to be covered in the summerschool are:
- Modelling of atomisation by different approaches
- Modelling of droplet break-up and collisions
- Modelling of droplet evaporation and combustion
- Numerical prediction and validation for spray
processes
- Applications, such as sprays in engines, spray drying,
spray cooling, spray coating
Additionally, lectures on recent advancements on single
point spray
measurements and imaging methods for spray analysis will be
given.
