Abstract: One of the most important problems in the operation of a salinity gradient solar pond is the stability of boundaries between gradient zone and convective zones. Although mach progress has been made recently, there are still many clarifications such as the mechanism of the heat and mass transfer through the gradient-convective boundary and the kind of dynamic processes that influence the gradient stability. In order to obtain an improved understanding of these dynamic processes, experimental studies have been conducted in a laboratory thermohaline system which is similar to solar ponds. Based on Particle Image Velocimetry (PIV) visualization-experiments and quantitative measurements, physical mechanisms of these processes are discussed.
