Description/Abstract | A series of four solar pond tests, conducted from September 1982 to August 1983, were completed to observe the ability of several immiscible fluids to absorb and store solar energy.^The tests were conducted in two adjacent laboratory insulated ponds, approximately one cubic yard in size.^The change in the fluid characteristics, i.e. spectral transmittance, vertical stability, biocide impact and clarity, were also examined following prolonged exposure to sunlight, wind and the additional of ambient dust and debris.^The simultaneous and comparable performance of heat storage in the immiscible ponds versus the conventional salt gradient solar pond was also briefly compared.^Candidate fluids considered were pearl kerosene, transformer oil, mineral oil, water, salt water (up to 20% salt by weight), methylsalicylate, and glycerin.^These choices were selected based upon readily available materials vs. costs and the range of fluid properties they presented.^Both convective and non-convective three-layered ponds were considered.^The results indicated a more rapid warm-up behavior by the immiscible fluid ponds versus the salt gradient test pond.^Higher bottom temperature were also reached (i.e.^184/sup 0/F in 45 days) and a faster recovery and continued warm-up rate observed for the immiscible ponds following intentional, mild, disruption of the vertical stratification. |
