Experimental analysis of the temperature and concentration profiles in a salinity gradient solar pond with, and without a liquid cover to suppress evaporation

New comprehensive investigation on the feasibility of the gel solar pond, and a comparison with the salinity gradient solar pond

“…Equation 6 will be: (8) where and are respectively the convective heat transfer coefficient between the gel layer and the UCZ, and between the LCZ and the gel layer. Their values are 56.58 and 48.279 W/m 2 K respectively [35]; is the thickness of the gel layer in meters, and is the thermal conductivity of the gel layer in W/m K.…”

“…There are many types of non-convective solar ponds: the salinity gradient solar pond (SGSP), the membrane pond, and the gel pond. In these ponds, heat transfer by convection is suppressed by the middle layer of the water body [8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

The investigation of using phase change material for solar pond insulation

“…The heat storage capacity of the system was improved by using transparent partial covers. Sayer et al [3] investigated the effect of evaporation on heat loss from the surface of a solar pond. Evaporation increases the cost of the system as well as decreasing its performance.…”

Behaviour of a salinity gradient solar pond during two years and the impact of zonal thickness variation on its performance

“…there is no convection in this zone and consequently heat moves upward only by conduction from the LCZ to the UCZ through the NCZ [16][17][18][19][20]. Existence of the NCZ is the key to the operation of a SGSP [21][22][23][24].…”
