Considering the analogical equation for mass transfer with the kinematic energy equation, a new eddy diffusivity is defined in much the same way as the eddy viscosity presented in the previous paper5). Being different from the conventional eddy diffusivity, the newly defined eddy diffusivity can be determined uniquely on the notice point from a single mean concentration gradient to any direction at that point. At the transitional region from laminar to turbulent flow of liquid in a circular pipe, further, experimental values of the newly defined eddy diffusivity are obtained by simultaneous measurment of the liquid velocity fluctuations and the concentration fluctuations of injected tracer by electro-chemical techniques.
