A vortex is intuitively recognized as the rotational/
swirling motion of a fluid. Vortices are ubiquitous in 
nature and are viewed as the building blocks, muscles, and
 sinews of turbulent flow. A mathematical definition of a 
vortex has been absent, and the lack of an accurate and 
quantifiable definition is a hindrance to the study of fluid dynamics.

This hybrid international conference aims at academic 
exchanges between worldwide scientists and engineers toward
 world consensus on the vortex definition and prediction. We
 are looking for an accurate mathematical vortex definition
 in fluid dynamics by brainstorming among all vortex-related
 researchers around the world.

This goal has become urgent due to recent advances in 
theoretical, computational, and experimental vortex 
dynamics, especially in human-faced problems such as 
turbulence, severe weather including tropical cyclones and 
tornadoes, cardiac blood flow, etc.

The wide impact will include almost all fluid-related 
research areas such as aerodynamics, thermal dynamics, 
hydrodynamics, oceanography, meteorology, metallurgy, civil
 engineering, astronomy, heart and respiratory flows, etc. 
Any new ideas, methods, and applications related to vortices
 are welcome to attend this forum. The conference 
proceedings will be published by a professional publisher.
