Abstract:

Solar power towers can be used to make hydrogen on a large scale. Electrolyzers could be used to convert solar electricity produced by the power tower to hydrogen, but this process is relatively inefficient. Rather, efficiency can be much improved if solar heat is directly converted to hydrogen via a thermochemical process. In the research summarized here, the marriage of a high-temperature (∼1000°C) power tower with a sulfuric acid∕hybrid thermochemical cycle was studied. The concept combines a solar power tower, a solid-particle receiver, a particle thermal energy storage system, and a hybri

Abstract:

This paper presents a test method for determining the thermal loss from a solar central receiver at normal operating conditions. The thermal loss determined by this test method is independent of knowing the incident solar power onto the receiver. Thermal loss includes losses from emitted radiation, convection, and conduction. Reflected radiation is accounted for by an effective solar absorptance. The paper describes the test method and derives the equations used to evaluate the receiver thermal loss from the test.

Abstract:

Se analizaron los posibles efectos de la actividad solar en la temperatura superficial del aire y precipitación en Centro América. La correlación entre las series de manchas solares y las variables climáticas mencionadas es pobre. No obstante, se observó una tendencia creciente en los datos durante el periodo considerado. Usando el análisis de Fourier se encontraron picos de frecuencia aproximadamente a los 11 años y 5 años. Esto sugiere que la actividad solar puede ser un factor que afecta las variables climáticas.

AbstractStudies stimulated by the interpretation of the Elatina formation in South Australia as a fossil record of solar activity have led to discoveries of previously unnoticed features of the sunspot cycle record and to a theory of origin of the sunspot cycle that postulates a solar core in torsional motion and a magnetomechanical wave that couples to the photosphere. The considerations supporting the solar interpretation of the Elatina formation are gathered together.

Results are presented from a numerical model of the steady-state energy transfer in molten-salt-in-tube solar cavity receivers that includes convective energy transfer at a local (spatially resolved) level.

This model is applied to the Molten Salt Subsystem Component Test Experiment (MSS/CTE) cavity receiver. Results for this receiver indicate the global (entire cavity) receiver thermal efficiency is invariant within a few percent to most parameters investigated, although front surface temp

Abstract:

AbstractSolar five-minute oscillations provide a means of testing theoretical models of the sun. By judiciously combining data from low-degree modes, properties of the central and surface regions of the sun can be inferred separately. In principle, it should be possible to draw similar inferences from other stars, once adequate data are available. Recent solar rotational splitting data imply that in the equatorial regions much of the radiative envelope of the sun is rotating more slowly than the photosphere.

Abstract. We report on the effect of solar variability at the 27-day and the 11-year timescales on standard phase height measurements in the ionospheric D region carried out in central Europe. Standard phase height corresponds to the reflection height of radio waves (for constant solar zenith distance) in the ionosphere near 80 km altitude, where NO is ionized by solar Lyman-α radiation. Using the superposed epoch analysis (SEA) method, we extract statistically highly significant solar 27-day signatures in standard phase heights. The 27-day signatures are roughly inversely correlated to solar

Solar retinopathy (SR) results from unprotected solar eclipse viewing and also from gazing at the sun for a long duration.

We report a case of CSCR associated with solar eclipse viewing.

Heat loss is an important factor in the performance of the solar receiver for concentrated solar systems (CSP). This study presents a proposed model for a new design for the receiver using an evacuated tube that has been performed to reduce convection loss and radiative heat losses with a zigzag distribution to minimize spillage losses. In this study, simulation results showed that the energy input increases with increased solar irradiation; the increase ranges from 3429 to 5584 W and 1879 to 3875 W at 9 AM and 13 PM for preheater and superheater respectively. The thermal efficiency of the rec

Abstract:

A complete technical study on a Hybrid heating system is carried out with the aid of computer simulation. The main objective of this work was to provide more insight into combining Solar and Diesel energies to be utilized in domestic central heating. The motivation for such a system was basically the ever increasing Diesel prices in the Kingdome. This work revealed that the cost of Diesel in heating houses could be lowered by at least fifteen percent if the hybrid system is implemented. Complete mathematical model of a representative house was derived for the sake of computer simulation. The m
