On the Extraction of Long-living Features in Unsteady Fluid Flows
Mathematics and Visualization
This paper proposes a Galilean invariant generalization of critical points of vector field topology for 2D time-dependent flows. The approach is based upon a Lagrangian consideration of fluid particle motion. It extracts long-living features, like saddles and centers, and filters out short-living local structures. This is well suited for analysis of turbulent flow, where standard snapshot topology yields an unmanageable large number of topological structures that are barely related to the fewdoi:10.1007/978-3-642-15014-2_10 fatcat:z4d4dsa23vdftl6pqpwsjkbxqa
