TURBULENCE IN WAKES OF IDENTICAL VELOCITY (TURBULENTNOST V SPUTNYKH POTOKAKH ODINAKOVOI SKOROSTI),

Abstract

The turbulence transfer from a turbulent stream discharging from a plane nozzle into a liminar stream moving at the same velocity is considered. The model is based on the mixing processes with eddy diffusion occurring across the flow interface. Based on arguments that the mixing coefficient (probability of turbulence at a given point) has a normal distribution and that the eddies interact only weakly among each other, it is assumed that the distribution of pulsation energy can be described by the normal diffusion equation.
