Summary on Grant Application Form |
|
The primary aim of this proposal is to develop systematic methods for investigating the internal structure of singular flow topologies or complex eddies and testing these on defined complex eddy patterns. We propose to use fractal-type scaling measures to probe the structure of DNS turbulent vortex tubes, and wavelet transforms to analyse and simulate small-scale turbulence. New families of exact or approximate vortex tube solutions to the Navier-Stokes equations will be investigated and will constitute the basis for our choice of wavelets. The wavelets will be determined accurately from the fractal-type analysis of the scaling properties and the topology of streamlines around DNS vortex tubes. 1-D versions of these wavelets will be used to analyse experimental data in a parallel attempt to educe small-scale turbulence singular structure from experiment. The work will be extended to turbulent Lagrangian trajectories, and the implications of our results for three types of turbulence modelling will be investigated; Lagrangian, wavelet expansions and calculation of sub-grid stresses.
