Analysis of turbulent flows


The analysis of transitional and turbulent flows is focussed on vortical nature of these flows, particularly on vortex-identification methods. In the field of identification, it deals with shearing bias of identification methods, their applicability to compressible flows, sensitivity of identification methods to axial stretching rate of vortices, and other factors. The investigation is predominantly based on the analysis of the velocity-gradient tensor, suitable decomposition methods near a point, including the search for an adequate kinematic interpretation.
