Towards understanding the structure of turbulence Seminar

Speaker information

Dr Sotos Generalis , Aston University. 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.
