Studies of Natural Convection at Vertical Electrodes

Abstract

The hydrodynamic flow near vertical electrodes in electrolysis with natural convection was studied optically. The velocity distribution was measured for various experimental conditions. The flow velocities are calculated for the case of a constant current density along the electrode by the von Kármán ‐Pohlhausen integral method and compared with the experimental data. In the theoretical derivation various assumptions are made concerning the shape of the velocity and concentration profiles, and their influence on the computed values of the maximum flow velocities is discussed.

“…The third, and most plausible explanation, was given by Wagner 23 and Ibl and Müller 24 , which described convective ascending fluid motion caused by different densities between the diffusion layer and liquid bulk. During an electrodeposition process, if the limiting cathodic current is surpassed, reaction rates are determined by species diffusion rate, leading to its depletion within the diffusion layer, when compared to bulk.…”

“…91 Nonetheless, it seems likely that settings of Dies sanctificatus, Senex puerum portabat, Puer natus, O sacrum convivium, Terra tremuit and Psallite domino recorded in the minute books as having been sung occasionally at meetings in the later 1740s and 1750s were those by Byrd. By 1816, as we know from an index to the library presented in that year, 92 the partbooks of the society included the Kyrie and Gloria of the Mass in Three Parts, 93 Emendemus in melius, 94 Laudate, pueri, dominum, 95 O quam gloriosum 96 and Quodcunque ligaveris. 97 The society also owned complete copies in score of Gradualia I and II 98 and of the Mass in Four Parts.…”
