We present an approach to analyze mixing in flow fields by extracting vortex and strain
features as extremal structures of derived scalar quantities that satisfy a duality property …

Vector field topology is one of the most powerful flow visualization tools, because it can
break down huge amounts of data into a compact, sparse, and easy to read description with …

Analyzing large and high-dimensional flow data sets is a non-trivial task and favorably
carried out using sophisticated tools which allow to concentrate on the most relevant …

Scale-space techniques are very popular in image processing since they allow for the
integrated analysis of image structure. The multi-scale approach enables one to distinguish …

This paper provides key insights into the construction and evaluation of interpersonal
simulators-systems that enable interpersonal interaction with virtual humans. Using an …

It is a challenging task to visualize the behavior of time-dependent 3D vector fields. Most of
the time an overview of unsteady fields is provided via animations, but, unfortunately …

We propose a new criterion to characterize hierarchical two‐dimensional vortex regions
induced by swirling motion. Central to the definition are closed loops that intersect the flow …

Turbines are core components in jet engines for flight propulsion, power plants, and other
important energy conversion processes. They are composed of successive rows of blades …

Even though the analysis of unsteady 2D flow fields is challenging, fluid mechanics experts
generally have an intuition on where in the simulation domain specific features are …

Line integration of stream-, streak-, and pathlines is widely used and popular for visualizing
single-phase flow. In multiphase flow, ie, where the fluid consists, eg, of a liquid and a …
