Control of the growth of the diffusional boundary layer on a rotating axisymmetric electrode of arbitrary shape in an ostwaldian fluid

Using a suitable coordinate transformation, an analysis is first described for the prediction of the velocity distribution in a laminar boundary layer flow near a rotating axisymmetric electrode of arbitrary shape in an Ostwaldian fluid, by expressing the governing conservation equations in a series representation universal with respect to electrode contour parameters, patterned by Blasius procedure.Using the first leading term of the series, we define the profiles of the electrodes which fulfil the diffusional limiting density flux j_x = j₀$\text{x}$^p, in which j₀ is an independent coordinate coefficient, p is a numerical power-factor and $\text{x}$, is measured along the direction of the longitudinal component of the flow. The relation between the permitted values of p with the behaviour coefficient of the fluid is described. The particular case of the uniformly accessible electrode (p = 0) is discussed.
