Abstract
A numerical method is described which can be used to calculate the development downstream (or in time) of the energy spectral density distribution (over the modulus of the wave-number vector) of homogeneous isotropic turbulence in the entire wave-number range. The effect of the step in the modulus of the wave-number vector on the accuracy of the calculation is investigated. The results of a calculation of the process of degeneration of homogeneous isotropic turbulence are presented along with some integral characteristics of the spectrum. The results of the calculation are compared with experiment.
