Viscous Fingering: A Topological Visual Analytic Approach
We present a methodology to analyze and visualize an ensemble of finite pointset method (FPM) simulations that model the viscous fingering process of salt solutions inside water. In course of the simulations the solutions form structures with increased salt concentration called viscous fingers. These structures are of primary interest to domain scientists as it is not clear when and where visco...
متن کاملViscous Fingers: A topological Visual Analytic Approach
We present a web-based visual analytics framework to visualize viscous fingers that combines particle systems, direct volume rendering, and graphs. In our first step, we apply a Gaussian filter to the particle dataset to obtain a voxel representation for the entire computational domain. Next, we extract and track the viscous fingers using Reeb graphs, where the fingers are treated as level sets...
متن کاملFluctuations in viscous fingering.
Our experiments on viscous (Saffman-Taylor) fingering in Hele-Shaw channels reveal finger width fluctuations that were not observed in previous experiments, which had lower aspect ratios and higher capillary numbers Ca. These fluctuations intermittently narrow the finger from its expected width. The magnitude of these fluctuations is described by a power law, Ca(-0.64), which holds for all aspe...

متن کاملNonextensive statistics in viscous fingering
Measurements in turbulent flows have revealed that the velocity field in nonequilibrium systems exhibits q-exponential or power law distributions in agreement with theoretical arguments based on nonextensive statistical mechanics. Here we consider Hele-Shaw flow as simulated by the Lattice Boltzmann method and find similar behavior from the analysis of velocity field measurements. For the trans...
