Dr Sotos Generalis's research concentrates on the numerical solution of the strongly non-linear Navier-Stokes equations as applied to the stability problems concerning incompressible plane-parallel shear flows. 

The non-linear Navier-Stokes equations are solved with the aid of a Galerkin-type technique in order to identify the hierarchical transition to turbulence. The (generalized) case of transition of fluid flow patterns from the laminar stage to the early stages of the turbulent regime in plane parallel shear flows is a major subject in the fluid dynamics research because of its considerable importance to applications in engineering and geophysics. 

Theoretical investigations aided by the advance of powerful hardware coupled by parallel experimental studies of plane parallel shear flows have provided significant insights in identifying the transition mechanisms from laminar to turbulent flow. Recent work on the strongly non-linear studies of Couette flow have appeared on the cover issue of the Physical Review Letters. 

Dr Generalis has also worked in the application of computational fluid dynamical techniques to a variety of problems in polymer processing, complex reaction mechanisms and reactor design.

I welcome enquiries from PhD-qualified researchers from all countries outside the UK that wish to apply for a Marie Curie Fellowship to come and work with me at Aston; the next call opens on 14th March 2017 with a deadline of 14th September 2018. The Fellowship Scheme available:

  • For early- to mid-career researchers of any nationality currently working in Europe
  • For researchers at mid-career plus working in any country outside of Europe 

Subject areas include transition to turbulence for shear flow, probing the structure of turbulence in shear flows and bifurcation sequences of (coupled) canonical flows. Please contact me directly for further details.

Leverhulme Trust Research Grant

The intermediate particle flow: multiscale experiments and modelling

with Dr Yassir Makkawi (PI) and Professor Rafaela Ocone (CI) 

Royal Academy of Engineering Distinguished Fellowship Scheme 

Professor Fujimura, (Tottori University, Japan)

Duration: One month (March 2012) 
Prof Fujimura has developed techniques for establishing bifurcating secondary flow, responsible for the momentum and mass transfer in the channel of fluid flow, that are powerful devices applicable in the vicinity of the stability boundary of the laminar shear flow.
This technique will be combined with the fully non-linear programmes that exist at the involved.host Institution. This will create a new generation of programmes that will in turn incubate graduates to become engineers that have intimate knowledge of the mechanisms.

The Leverhulme Trust Visiting Professorship 

Professor Friederich Busse

VP1-2012–017 (Period: 2013 - 2015) 

The main aim of this proposal is to understand the structure of turbulence in shear fluid flow. Professor Busse is a world leading authority in the field and will closely interact with the Dr Generalis and the wider Aston Mathematics Department in order to unravel the structure of turbulence, offering the possibility for widespread practical engineering benefits. An additional aim is to bring together two authorities in their field - Professor Busse (fluid dynamics) and from Aston Electronic Enginering Department Professor Turitsyn (photonics) - and through mutual interaction and drawing from fluid dynamical analogies adapt, enhance and extend existing theoretical approaches and numerical tools to the problem of optical wave turbulence.
