Title: Turbulent Flows, Universality and Emergence

Abstract:
Turbulent flows are paradigm cases of complex systems where multi-scale 
modelling is required. The fundamental problems in the field are strong 
fluctuations and couplings – problems that are also present in condensed 
matter physics (CMP) and field theory. Like the latter two areas of 
physics, renormalization group methods have been used to treat some of 
the theoretical difficulties with turbulent flows. However, unlike CMP 
where universality and emergence is, in some sense, reasonably 
understood, it is less than straightforward in cases of turbulence. I 
examine some of these issues, in particular the relation between 
multi-scale modelling and emergence, in an attempt to clarify how or 
even whether a notion of emergence might be applicable in the context of 
turbulent flows.
