This article evaluates the influence of several parameters interacting in the electrical, thermal, and electro-osmotics phenomena that rule the transient/dynamic behavior of the soil temperature rising process. The aim is to provide a safe design of ground electrodes concerning the risk of soil collapse ("vitrification") as a consequence of thermal instability. An objective electro-osmosis modeling rather accurate, applicable to generic geometries of ground electrodes, not only for homogeneous… CONTINUE READING
