High Temperature Solar Concentrators
نویسنده
چکیده
The use of solar energy in technical applications is often constrained due to its low energy density relative to the conventional sources of energy. Optical concentration is one option to increase the energy density of the solar radiation resulting in the possibility to use absorbers with small surfaces. Higher temperatures can be achieved under concentrated conditions, because heat losses are proportional to the absorber surface. If the final objective is to convert the solar energy into work, the thermodynamics suggests that it can be done more efficiently the higher the temperature is.

Comparison of Solar Concentrators
-Even though most variations of solar concentrators have been studied or built at some time or other, an important class of concentrators has been overlooked until very recently. These novel concentrators have been called ideal because of their optical properties, and an example, the compound parabolic concentrator, is being tested at Argonne National Laboratory. Ideal concentrators differ radi...
متن کاملDesign and Analysis of a High - Efficiency , Cost - Effective Solar Concentrator
Solar concentrating systems are optical systems that concentrate solar energy for conversion into usable energy. Ideally, a solar concentrating system should have the following favorable properties as design criteria: (i) energy-efficient, (ii) cost-effective to construct, and (iii) highly durable and costeffective maintain, even in the presence of high temperature variations, wind and sand loa...
متن کاملWhite butterflies as solar photovoltaic concentrators
Man's harvesting of photovoltaic energy requires the deployment of extensive arrays of solar panels. To improve both the gathering of thermal and photovoltaic energy from the sun we have examined the concept of biomimicry in white butterflies of the family Pieridae. We tested the hypothesis that the V-shaped posture of basking white butterflies mimics the V-trough concentrator which is designed...

متن کاملCarbon dioxide as working fluid for medium and high-temperature concentrated solar thermal systems
This paper explores the benefits and drawbacks of using carbon dioxide in solar thermal systems at medium and high operating temperatures. For medium temperatures, application of CO2 in non-imaging-optics based compound parabolic concentrators (CPC) combined with evacuated-tube collectors is studied. These collectors have been shown to obtain efficiencies higher than 40% operating at around 200...
متن کاملNatural convection heat transfer in V-trough solar concentrators
The use of V-trough concentrators offers a simple approach to increasing the radiation incident on a solar receiver; this is particularly useful for increasing the temperature in thermal systems. However in order to accurately predict the performance of thermal systems under concentrated radiation, there is a need to understand the heat loss from them. This study experimentally shows that, for ...
