Properties of Turbulence with Zero and Nonzero Helicity

Research output: Working paper/PreprintPreprint

Abstract

The present paper deals with the study of spectral properties of the helical mode of uniform isotropic turbulence in the presence and in the absence of mean helicity. It is shown that even in the absence of mean helicity, the helicity of individual helical modes affects the spectral behavior of turbulence. Besides, it is shown that both with and without mean helicity, intermediate characteristic scales connected with the presence of helicity in helical modes exist. The existence of such scales makes it possible to solve the problem of helicity dissipation divergence for individual helical modes.
