The color graphic above a transmission electron microscope image of the vortex core shows the trapped spins moving around the permalloy sample, which then generate the conical vortex core rising out ...

The study of vortex dynamics in fluid mechanics is critical for both advancing aeronautical design and minimising flow-induced hazards. At its core, vortex dynamics examines the formation, evolution, ...

Figure 1: Dynamical reversal of the vortex core: The upper section shows the "magnetic needles" of the vortex core, pointing down on the left and up on the right. The lower section shows these two ...

Vortex identification and turbulent flow analysis have evolved considerably from early vorticity‐based techniques to modern, quantitative methods. Traditionally, researchers used measures such as ...
