The process of loss of internal stability in salt gradient solar ponds

Abstract

Loss of the bulk stability in salt gradient solar ponds is a rather rare, short duration phenomenon, which can lead to complete mixing of the gradient zone. Laboratory investigations have allowed close observation of this phenomenon and comparison of the derived data with theory. It is shown that there is little or no probability of such instability occurring with the maximum salt concentration normally used (about 20% at the bottom). Boundary erosion of the gradient zone is an entirely unrelated matter.
