The Hanging-Meniscus Rotating-Disk (Hmrd) .1. Dependence of Hydrodynamic Behavior on Experimental-Variables
The hydrodynamic behavior of the hanging-meniscus rotating disk (HMRD) has been studied under different experimental conditions. The HMRD is a configuration that allows an electrode material to be studied without being mounted in an insulating shroud. The influence of experimental variables such as electrode material, electrode diameter and meniscus height is discussed. A correction term which accounts for the differences in hydrodynamic boundary conditions introduced in the standard Levich equation allows the slope and the small negative intercept of Levich plots for the HMRD as well as the dependence on experimental variables to be explained. Conditions for the proper use of this configuration are also established.
