Within the field of fluid dynamics, Homogeneous isotropic turbulence is an idealized version of the realistic turbulence, but amenable to analytical studies.
The concept of isotropic turbulence was first introduced by G.I.
Taylor also suggested a way of obtaining almost homogeneous isotropic turbulence by passing fluid over a uniform grid.
The theory was further developed by Theodore von Kármán and Leslie Howarth (Kármán–Howarth equation) under dynamical considerations.
Kolmogorov's theory of 1941 was developed using Taylor's idea as a platform.
