In this paper, free heat transfer ( H T ) and the entropy generation ( E g e n ) of Alumina/ H 2 O nanofluid (NF) in an square cavity (CV) are simulated owing to its application in solar collectors. For this purpose, a square CV with an angle γ is placed

A building integrated solar collector: All-ceramic solar collector
Energy and Buildings, 2013Abstract A type of all-ceramic flat plate solar collector is introduced. These all-ceramic solar collectors are made from ordinary ceramic and V–Ti black ceramic. The solar absorptance of black ceramic coatings is in the range of 0.93–0.97. The all-ceramic solar collector is characterized by low cost, long lifetime, no attenuation of absorptance, and

Luminescent Solar Collectors: Quo Vadis?
Advanced Energy Materials, 2020Luminescent solar concentrators (LSCs) are optical systems that absorb, convert, and concentrate solar light by means of photoluminescence of an emitting material embedded in a transparent waveguide. LSCs combine large possibilities of variation of shape,

Rational use of energy in buildings leads to a concept of active energy facades such as transparently insulated massive walls, solar thermal or PV facades, advanced glazings for daylighting purposes or double ventilated facades. The paper is concerned with the facade-integrated solar thermal collectors concept for water heating in the existing building

A Recuperative Solar Collector
International Journal of Solar Energy, 1985This investigation is a theoretical and experimental study of a recuperative type solar water heater where water is allowed to pass through the two upper transparent covers in channel flow before flowing through the tubes of the collector. The water in the channel will be first heated by solar insolation absorbed in the fluid layer and by the upper ...

Abstract Details of the design and development of an inexpensive solar collector system which does not make use of a blackened metal plate as an absorber are given in this paper. A spiral-shaped plastic tube coated with a black paint constitutes the solar absorber.

This chapter presents a detailed description of energy balance for solar collector and of different types of solar thermal and photovoltaic (PV) collectors including the calculation of their efficiency and new materials for PV cells. The discussion considers both concentrating and nonconcentrating thermal technologies. Additionally, a brief overview on

Efficiency of solar collectors
Energy Conversion, 1976Abstract Flat plate and concentrating-type solar collector efficiencies are determined at different temperatures using plain black and selective absorbing surfaces with plain glass and specially coated reflecting glass windows and at different air masses.
