Heat loss modeling for the ANL Research Solar Pond
An analytical capability has been developed based on using the COMMIX-SA-SP code to analyze the transient three-dimensional heat losses from an arbitrarily shaped solar pond. The COMMIX-SA-SP code is derived from the COMMIX-1A code. The analytical capability is demonstrated by calculating the heat losses from the ANL Research Solar Pond, which is under construction in Argonne National Laboratory. The calculations show that the two-dimensional model underestimates the heat losses as compared with the three-dimensional model. The yearly average heat flux approaches to within 10% of the steady state value after approximately 5 years of operation. Weather changes during the year create flux changes up to 4 times the average value. An insulator with thermal conductivity to thickness ratio less than 0.12 W/m/sup 2///sup 0/K can reduce the heat loss from a solar pond to soil by 50% or less.
