What is taylor green vortex?

The Taylor-Green vortex is a 3-dimensional flow field that is used as a benchmark problem in fluid dynamics. It is named after the scientists G. I. Taylor and A. E. Green, who first studied the flow in 1937. The Taylor-Green vortex is created when a fluid is stirred by two perpendicular blades, creating vortices that interact and form a complex flow field. The flow is characterized by its periodicity, and the formation of smaller vortices that are created by the larger ones. The Taylor-Green vortex is used to test numerical simulations and experimental techniques in fluid dynamics, as it is a well-understood problem with known solutions. It is also relevant to many real-world applications, such as the study of turbulence in aircraft engines and weather prediction.
