TL;DR: In this paper, a computer model for predicting the thermal performance of domestic solar water heaters, employing thermosyphon circulation between the collector and the insulated storage tank, is described.

TL;DR: In this paper, a way to use honeycomb panels (anti-radiating cellular structure) for the thermo-dynamic conversion of solar energy into electric energy at high temperatures is described.

TL;DR: In this paper, the heat and mass transfer relationship of a solar still in the unsteady state can be solved graphically by means of a characteristic chart, which expresses the various heat fluxes as functions of the cover temperature.

TL;DR: The possibility of installing solar energy devices such as air conditioning plants, solar desalination stills, etc. in remote parts of Australia has led to the necessity of predicting solar radiation in places where no measurements have been made as mentioned in this paper.

TL;DR: In this paper, the design of combined solar collection and storage systems for house heating requires careful integration and optimization to minimize unfavorable economics, because the environmental factors are highly variable with time, hourly performance over a season must be considered to accurately assess economic problems.

TL;DR: In this paper, an experimental investigation was made to determine the heat capacity of solutions of sodium thiocyanate in liquid ammonia at varying concentrations and temperatures, together with already existing heat of solution data, were used to generate a temperature-enthalpy diagram for the combination.

TL;DR: In this paper, a study of a solar-energy collector that heats air is described, where the collector is installed in a glass covered box so that air can be pumped past the aluminum fins for heating.

TL;DR: In this paper, nine years of daily insolation observations taken at Blue Hill, Massachusetts, were correlated, by month, with observations of temperature, snow cover, winds, sunshine, sky cover, pressure and precipitation.

TL;DR: In this paper, the authors reviewed instruments and results of Eppley-JPL program using high altitude jet aircraft and rocket research vehicle for solar constant measurement, and showed that the results showed promising results.

TL;DR: In this paper, statistical and experimental methods are used to determine the optical efficiency and the heat lost by radiation and convection in a horizontal plastic solar hot water heater, which consisted of a water filled polyethylene bag with a clear top and black bottom.

TL;DR: In this paper, a special filtering system was developed to change the operation of the Model X-25 Xenon Arc solar simulator to air mass two (average sea level) sunlight, and the developmental problems associated with design, construction analysis and measurement of the special air-mass two filter were discussed.

TL;DR: In this paper, photodegradation of organic polymers by UV radiation exposure, emphasizing polyvinyl chloride photochemistry and radiation stabilization, is discussed, and a method for radiation stabilization is proposed.

TL;DR: In this paper, a model for predicting the liquid holdup was proposed, as a function of liquid flow rates, liquid properties and liquid-distributor properties, and the correlation coefficient between the observed holdup and the corresponding calculated holdup is R = 0·944.

TL;DR: In this article, the spectral distribution from ground level, rocket and satellite observations to obtain value of energy received at top of the atmosphere was used to estimate the energy received from solar electromagnetic radiation spectral distribution.

TL;DR: In this article, the spectral distribution of solar irradiance at the mean Sun-Earth distance and in the absence of the Earth's atmosphere have been compared with similar data published in recent years by six other authors.

TL;DR: In this paper, the authors suggested mechanisms by which the additives effectively screen the polymer from damaging radiation, and discussed the factors, such as absorption in the u.v. region, inherent stability of the additive, and compatibility of additive and polymer, which influence the selection of a stabilizer system.

TL;DR: In this paper, a pulse shaper has been constructed which will produce the standard nuclear weapon puise shape in the Natick Laboratories solar furnace, where an array of 16 radial vanes, each about 1 1 2 M ft long, is placed in the converging beam about 40 in in front of the focus.
