A Vorticity Based Model of Isotropic Turbulence

ABSTRACT

It is argued that the transfer operator in the governing equation of isotropic turbulence is engaged in convection of turbulent energy. Pursuing this argument the transfer operator is replaced by a constant multiplier and vorticity of dimension same as that of the transfer operator. Thereafter the general decay of isotropic turbulence is studied. An expression of longitudinal correlation coefficient is found and plotted against the separation distance between two close points of measurement. The new result is compared with the standard one.
