The paper deals with the modeling of degeneration of isotropic turbulence. Simulation of a turbulent process is based on the filtered three-dimensional unsteady Navier–Stokes equations. For the closure of the main equation used viscous model. The problem is solved numerically, the equation of motion is solved by a modified method of fractional steps with compact scheme, the equation for pressure is solved by the Fourier method, in combination with a matrix factorization. The simulation obtained change of turbulent kinetic energy by time, micro-scale turbulence, change of longitudinal-transverse correlation functions, defined by longitudinal and transverse one-dimensional spectra.
Mots-clés : isotropic turbulence, microscale turbulence.
Keywords: Navier–Stokes equations, longitudinal-transverse correlation functions
