Fifth Meeting: Hewitt-Reese Spring School in Modelling Multiphase Flows


This year sadly witnessed two pioneering fluid dynamicists passing away, Prof Geoff Hewitt and Prof Jason Reese. Both Geoff and Jason made significant contributions towards mathematical modelling of multiphase flows. And both were immensely supportive of his PhD students, aspiring academics and researchers across the board.

So, in their honour, our Special Interest Group is organising the Hewitt-Reese Spring School for Modelling Multiphase Flows on May 14-15, in Strathclyde (Mathematics), Glasgow.

The Spring School is for PhD students, post-docs, academics, industry personnel  and or anyone with interest in fluid dynamics – to come together and look at the wide variety of modelling methods that may help reveal the underlying phenomena.

You may be:

  • a modeller trying to understand your modelling methods – we will cover a wide spectrum of multiphase modelling methods at all scales (Macro/ Meso/ Atomistic – and coupling methods in between!),
  • an experimentalist wishing to learn modelling methods that could help you understand the underlying phenomena,
  • interested in numerical methods, handling/ post-processing big data etc, or
  • just curious about flows in your area of work.

Key highlights:

  • 1.5 day Spring School covering a range of modelling methods for multiphase flows, including theoretical/ analytical, numerical and stability methods
  • Meet Jason’s and Geoff’s families. We will begin with tributes and also talks about their technical contributions.
  • FREE: 40 places for 1 night B&B and dinner. 5 left. SO HURRY UP! (Note: Early Career Researchers Only i.e. PhD students, Postdocs, New Academics, Travel is not covered).
  • Venue: Strathclyde University , Department of Mathematics and Statistics
  • Date: 14-15 May, 2019

Upcoming External Event: 4th Workshop on Advances in CFD, LB and MD Modeling of Capillary Two-Phase Flows and Experimental Validation, 16-19 May 2019, Rio de Janeiro, Brazil (The Workshop precedes ICMF 2019)

A world-leading international Workshop on the latest advances in the computational modelling of the interfacial dynamics of capillary two-phase flow phenomena using Computational Fluid Dynamics (CFD), Lattice Boltzmann (LB) and Molecular Dynamics (MD) methods. In addition, experimental two-phase flow visualization techniques will presented. The Workshop is now at its 4th edition, following the first two editions in 2016 and 2017 that took place at the EPFL in Lausanne, Switzerland, and the 2018 edition at Kobe University, Japan.

The international team of lecturers is as follows:

  • Prof. A. Tomiyama, S. Hosokawa and Prof. K. Hayashi (Kobe University),
  • Prof. J.R. Thome (University of Edinburgh),
  • Prof. G. Anjos and Prof. N. Mangiavacchi (State University of Rio de Janeiro),
  • Prof. P. Theodorakis (Polish Academy of Sciences) and
  • Dr. M. Magnini (Imperial College London).

Additional information can be found in the 2019 Workshop flyer

Workshop location and travel information

The Workshop will be held in Rio de Janeiro, Brazil; the exact location will be communicated soon. The end of the Workshop coincides with the beginning of the 10th International Conference on Multiphase Flow (ICMF 2019), which will take place in Rio de Janeiro on May 19th-24th, 2019. Further information about ICMF 2019 are available in the Event listed below in this page.

Workshop registration and inscription fee

The Workshop does not have any registration fee in order to promote the participation of students/researchers. When registering, participants will be invited to submit a brief personal overview of their research and interests in two-phase flow. As this is an advanced course, it is expected that participants already have a working knowledge of numerical fluid mechanics.

The registration deadline is April 1st, 2019. You are encouraged to register as soon as possible. A maximum number of 40 participants will be accepted.

The applicants will receive an email with the notification of their acceptance shortly after their registration.
