This paper discusses the design, construction, and initial operation of the solar pond at Los Alamos National Laboratory. This 232 m2 pond is the third facet of a threefold approach to the study of hydrodynamic effects in double diffusive systems, such as solar ponds. The first two facets are flow visualization experiments and one-dimensional laboratory tank tests [1]. Data from these experiments, in addition to other data from the literature, are used to validate the one-dimensional dynamic performance pond model developed by one of the authors [2]. Our particular interest is the boundary-layer structure at the interfaces between the convecting and nonconvecting zones, interaction between the zones, and surface zone effects including diurnal heating effects and wind-induced turbulence. A pond, such as the one this paper describes, provides possible insight into several pond physical processes that may not occur in smaller-scale laboratory experiments due to edge effects, or may be impossible to simulate.

Design Construction

A 3355 square meter, 3.3 m deep water storage pond in El Paso, Tex. was converted to a salt-gradient solar pond to supply industrial process heat to an adjacent food processing plant. Approximately 1.9 × 106 kg of sodium chloride salt was obtained to prepare near saturated brine for pond construction. Design and construction of the solar pond are described in detail including the lining technique, salt dissolution method, diffuser design, instrumentation, maintenance of optical clarity, and gradient establishment, including resolution of initial problems in gradient stability. The solar pond has been in continuous operation for over three years.

Abstract. In shallow thermohaline-driven lakes it is important to measure temperature on fine spatial and temporal scales to detect stratification or different hydrodynamic regimes. Raman spectra distributed temperature sensing (DTS) is an approach available to provide high spatial and temporal temperature resolution. A vertical high-resolution DTS system was constructed to overcome the problems of typical methods used in the past, i.e., without disturbing the water column, and with resistance to corrosive environments. This paper describes a method to quantitatively assess accuracy, precision and other limitations of DTS systems to fully utilize the capacity of this technology, with a focus on vertical high-resolution to measure temperatures in shallow thermohaline environments. It also presents a new method to manually calibrate temperatures along the optical fiber achieving significant improved resolution. The vertical high-resolution DTS system is used to monitor the thermal behavior of a salt-gradient solar pond, which is an engineered shallow thermohaline system that allows collection and storage of solar energy for a long period of time. The vertical high-resolution DTS system monitors the temperature profile each 1.1 cm vertically and in time averages as small as 10 s. Temperature resolution as low as 0.035 °C is obtained when the data are collected at 5-min intervals.

Double Diffusive

The possible influence of double-diffusive stratification on the vertical transport of salt and heat in a mixed-layer simulation model for a salt gradient solar pond is examined. The study is concerned primarily with the interfacial fluxes across the boundary between the gradient zone and upper convecting zone of solar ponds, though the arguments presented should be applicable to other “diffusive” interfaces as well. In the absence of mechanical stirring in the upper convecting zone (e.g., by wind), double diffusive instabilities could govern the vertical flux of heat and salt by adjusting interfacial gradients of temperature and salinity which control transport by molecular diffusion. Because these gradients are generally too sharp to be resolved by numerical models, the fluxes can either be modeled directly or be parameterized by grid-dependent “effective diffusivities.” It is shown that when mechanical stirring is present in the mixed layer, double-diffusive instabilities will not be allowed to grow in the interfacial boundary layer region. Thus, double-diffusive fluxes become important only in the absence of stirring and, in effect, provide a lower bound to the fluxes that would be expected across the interface.
