Some characteristics of turbulent flows with a zero margin of momentum

In the present paper, the Reynolds equation for averaged motion, in which normal turbulent stresses are taken into consideration, is used in combination with the energy pulsation equations to analyze the self-simulating development of a turbulent wake with a zero margin of momentum in the far field of the perturbing source. Allowance for the normal turbulent stresses leads to a structure of flow turbulence, whose characteristics differ from those of ordinary self-similar turbulent flows, primarily, in that the mean longitudinal damping rate is proportional to the mean-square pulsation rate, and the ratio of the turbulent shear stress to the mean square pulsation rate diminishes downstream.
