Exploring Flow Fields Using Fractal Analysis of Field Lines
نویسندگان
چکیده
We present a novel technique for analyzing the geometry of streamlines representing large scale flow fields produced in scientific simulations. We introduce the box counting ratio, a metric related to the Kolmogorov capacity or box counting dimension, for quantifying geometric complexity of streamlines (or streamline segments). We utilize this metric to drive a visual analytic framework for extracting, organizing and representing features of varying sizes from large number of streamlines. This framework allows the user to easily visualize and interact with the features otherwise hidden in large data. We present case studies using combustion and climate simulation datasets.

متن کاملSpatial Behaviour of Singularities in Fractal- and Gaussian Speckle Fields
Peculiarities of the spatial behaviour of the dislocation lines resulting from scattering of coherent radiation from random and fractal rough surfaces are studied. The technique of optical correlation is proposed for diagnostics of phase singularities in a complex speckle field by comparing the correlation lengths of amplitude and intensity of the local fields. It is shown that the dislocation ...
متن کاملReservoir Rock Characterization Using Wavelet Transform and Fractal Dimension
The aim of this study is to characterize and find the location of geological boundaries in different wells across a reservoir. Automatic detection of the geological boundaries can facilitate the matching of the stratigraphic layers in a reservoir and finally can lead to a correct reservoir rock characterization. Nowadays, the well-to-well correlation with the aim of finding the geological l...
