EMSI meeting Multiphase CFD

1
EMSI meetingMultiphase CFD

• G. Yadigaroglu
• Genova, June 26, 2004

2
Actions undertaken

• At the last EMSI meeting (Trondheim), Yadigaroglu
  was asked to inquire about non-nuclear CMFD
  applications, but did not receive any feedback,
  except information on the (rather nuclear) German
  initiative in CFD.
• Another e-mail inquiry on 12 May 2004 to all EMSI
  members produced a few reactions
• Prof. Ian A. Sutherland, Brunel Institute for
  Bioengineering, Brunel University doing some
  very interesting two-phase flow work in the
  bioprocessing field
• Prof. R.I. Issa, Imperial College
• The prediction of  two-phase (G/L, L/L, S/L)
  flows in mixing vessels
• Phase split at T-junctions (bubble and annular
  flows)
• Simulation of two and three phase slug flow in
  pipelines (using 1D transient model).
• Prof. Cees van der Geld, Eindhoven University of
  Technology Spectral-like Methods to Model
  Dynamic Gas-liquid Interface Deformation

3
Actions undertaken contd

• Prof. G. F. Hewitt, Imperial CollegeWe have
  done a lot of work on application of CFD codes to
  slug tail predictions etc.
• Prof. Ole Jørgen Nydal, NTNU CFD minded
  multiphase flow persons at NTNU are Hugo
  Jacobsen, Stein Tore Johansen, Inge Gran, Tor
  Ytrehus and maybe more no further reaction
  from them
• Dr. Hervé Lemonnier, CEA expecting to see some
  work from petroleum industry
• Letter from Prof. L. Friedel, TU Hamburg-Harburg
• CMFD can only complement calculations based on
  1D code predictions and explaining the reasons
  for this if 1D physical modeling is already not
  possible, any 3D modeling is then only a
  mathematical exercise without real physical
  background..
• I am ready to formulate a Round-Robin exercise
  on two-phase flow in a safety valvefor
  establishing the state of the art an
  interesting suggestion
• GYs appreciation a meager response should
  discuss possible actions/alternatives for the
  future. Maybe, for the time being, EMSI should
  concentrate on organizing the ETPFG meeting?
