Application of the polarographic method to the study of thermal free convection - The case of a horizontal cylinder
Abstract
Thermal convection is measured in a cylinder immersed in an electrolytic solution by means of the polarographic method. This method consists of measuring the critical ionic diffusion current at the level of a circular microelectrode which touches the surface of the resistance-heated cylinder. The diffusion current is plotted as the function of different temperature gradients. The dynamic and thermal boundary layers are evaluated.
