Taylor–Green vortex

The Taylor-Green vortex is a classic flow field used in fluid dynamics, particularly in the study of turbulence. It represents an example of a vortical flow that is mathematically derived and often serves as a benchmark for testing computational fluid dynamics (CFD) techniques and turbulence models. ### Characteristics of Taylor-Green Vortex: 1. **Velocity Field**: The Taylor-Green vortex has a periodic velocity field that can be described in two or three dimensions.
