A revised version of the "mesh step" model for the effect of a net type turbulence promoter on mass transfer in a narrow channel is presented . In the limit of a long channel the model is shown to yield a constant average boundary layer thickness the value of which is inversely proportional to the square root of the Peclet number. Mass transfer measurements using a ferro-ferri-cyanide electrochemical flow system snow that the model correctly predicts the dependence of the mass transfer rate on flow velocity and Schmidt number, and that on the mesh step in the range of large mesh step values. In the range of small mesh step values, it is shown that the effect of mesh step on mass flux is negligible and, hence, that this need not be a major consideration in the optimization of spacer nets within the usual range of application .

## Abstrac -This paper deals with the infiuence of cylindrical turbulence promoters on mass and energy transfers at the wall of a narrow channel with a Rowing liquid. The experimental distributions of the mass-transfer coefficients and shear stresses along the wall appear to be similar. The result
