| dc.description.abstract | Steady state voltammetry and the scanning methods were used to obtain voltammograms (current-potential curves) with well defined mass transfer regions. | en_US |
| dc.description.abstract | The Reynolds numbers were 7174, 10782, and 14307. The Schmidt number was held constant at 4730. | en_US |
| dc.description.abstract | The discrepancy among the experimental and literature-based values was in the range of 46% to 62%. This is due to the fact that the correlations cited in the literature were developed for simple molecules. | en_US |
| dc.description.abstract | The experimental local mass transfer coefficients (k's) were 2.43 x 10('-3), 3.15 x 10('-3), and 3.35 x 10('-3) cm/sec at Re = 7.74, 10782, and 14307 respectively. These experimental values of k's were compared with the literature by using the expression, | en_US |
| dc.description.abstract | The electrochemical technique was used to study the mass transfer rates of macromolecules in a flow system. The direct oxidation of NADH was the electroactive species. The flow system consisted of rectangular duct. Glassy carbon disc electrodes were used as the working electrodes. A platinum sheet was used as the counter electrode, and the reference electrode was Ag/AgCl. | en_US |
