Influence of artificial viscosity on the formation of vortex cascades in the shear layer

Numerical analysis of development of vortex cascades in a three-dimensional inviscid shear layer depending on the method of determining and the value of artificial viscosity is done. At the developed stage of turbulence the spectral analysis of kinetic energy is carried out and the law -5 3 of Kholm...

Description
Summary:Numerical analysis of development of vortex cascades in a three-dimensional inviscid shear layer depending on the method of determining and the value of artificial viscosity is done. At the developed stage of turbulence the spectral analysis of kinetic energy is carried out and the law -5 3 of Kholmogorov is confirmed. Pulsation and correlation functions of the flow are investigated.
