Lagrangian Visualization of Flow-Embedded Surface Structures
Abstract
The powerful yet conceptually simple notions of Finite-Time Lyapunov
Exponent (FTLE) and Lagrangian Coherent Structures provide a
powerful framework for the analysis and visualization of complex
technical flows. Their definition is simple and intuitive, and they
are built on a deep theoretical foundation. We apply these concepts
to enable the analysis of flows in the immediate vicinity of the
boundaries of flow-embedded objects by limiting the Lagrangian
analysis to surfaces closely neighboring these boundaries. To this
purpose, we present an approach to approximate FTLE fields over such
surfaces. Furthermore, we achieve an effective depiction of
boundary-related flow structures such as separation and attachment
over object boundaries and specific insight into the surrounding
flow using several specifically chosen visualization techniques. We
document the viability of our methods by presenting a number of
application examples.
Der Vortrag wird in Deutsch gehalten.
Alle Interessierten sind im Namen von Prof. Dr. Scheuermann herzlich
