A ROTATING DISC THERMOCELL. II. EXPERIMENTAL.
Abstract
A thermocell consisting of a rotating disc electrode and another wire electrode in an electrolytic solution is described. The temperature difference is produced by mounting a heater inside the rotating disc electrode while the temperature of the bulk solution is kept constant at a mean temperature of 21?C. The change of the thermoelectric power for 0.1 and 1.0 N aqueous KC1 solution with Ag/AgCl electrodes was independent of the speed of rotation below 375-400 rpm (laminar flow range). At speeds > 400 rpm the thermoelectric power values became dependent on the rotation speed, presumably because of increasing turbulence of the liquid. In the laminar flow range the mean values were 185 microvolts/deg and 250 microvolts/deg for 1.0 N and 0.1 N aqueous KC1 solutions, respectively. (Author)
