DESCRIPTION:Prof. Bernhard Weigand\, Institute of Aerospace Thermodynamics
 \, University of Stuttgart\nAbstract:\nThe numerical prediction of two-pha
 se flows is generally difficult. Normally a lot of simplifications and ass
 umptions have to been made. On the other hand\, a lot of two-phase flow ph
 enomena are present in our daily life and in a lot of technical processes.
  In many of these processes single droplets or interactions of droplets ar
 e of great interest (e.g. injection\, interaction and evaporation of fuel 
 droplets in a rocket or car engine or a gas turbine combustion chamber\, c
 louds formation\, rain droplets\, air pollution\, sprays in medical applic
 ations\,…). The ITLR in Stuttgart has developed over the past 20 years a
  CFD code named FS3D (Free Surface 3D)\, which is able to predict droplet 
 interactions\, droplet evaporation as well as jet instabilities by using d
 irect numerical simulation (DNS). The computational resources needed for t
 his approach are high\, so that the code is run normally on the supercompu
 ters in Stuttgart. Grid sizes of about several billion cells have been use
 d already successfully.\n \nIn this lecture several different application
 s of FS3D will be shown after a short explanation of the basics of a direc
 t numerical simulation. The examples range from droplet-droplet collisions
 \, splashing\, primary jet break-up to evaporating droplets and compressor
  fogging.
