Annotation

Based on the assumption put forward as to the local character of vorticity in a free incompressible liquid flow, the vortex element of a turbulent flow is isolated and its properties are evaluated. Good agreement is found to exist between the form of the spectral density of the velocity pulsations arising as a result of the uniform transport of a random ensemble of quasistationary turbulence vortex elements by the mainstream flow and the well-known approximations of experimental data.
