The IUTAM Symposium on Laminar-Turbulent Transition 2019

Date: 2-6 September 2019

Location: Imperial College London, UK

Scientific scope:  We have received unprecedented interest in the IUTAM Transition 2019. We received nearly 200 abstract submissions. We run
plenary sessions, individual talks and networking sessions. The scientific programme covered a range of fundamental topic areas, including:

  • Global analysis of instabilities and receptivities for complex configurations;
  • Nonlinear dynamical-systems approaches to minimal seeds and transition to turbulence;
  • Influence of multi-physics phenomena on transition: reactive flows, non-Newtonian material behaviour, interfacial flows, flows with interacting structures;
  • Novel experimental measurement and evaluation techniques for transition in complex flows;
  • Roughness-induced transition; transition from steps, gaps, junctions and other geometric imperfections;
  • Transition in hypersonic flows; prediction of thermal loads.
  • Active and passive control of flows undergoing transition; transition delay;
  • Transition mechanisms in natural and controlled environments; receptivity techniques and studies;
  • Late stages of transition and the breakdown to fully developed turbulence;
  • Transient growth problems and bypass mechanisms and their role in the transition process.


  • We received very positive feedback from attendees on the well organised and attended meeting.
  • Symposium was well attended by early-career academics, post-graduate students, industry representatives, senior members of the community and invited guests.
  • 175 registered delegates of which 40% are PhDs
  • Evening reception (Monday, 2nd September) and conferenced dinner (on the 5th September) provided networking opportunities for attendees to discuss future collaborations.
  • The conference proceedings will be published by Springer.
