Materials for high temperature solar container

Which materials are suitable for selective solar thermal applications?

A proper combination of container geometry, orientation, fins, nanoparticles, metal foams, and heat pipes could be considered for further research. The hybridization of sensible and latent heat storage materials could be investigated to suit the selective solar thermal applications.

Are solar absorber materials suitable for high-temperature operation?

One major barrier is the unavailability of suitable solar absorber materials for operation at higher temperatures. In this work, we report on a new high-temperature absorber material by combining Ti 2 AlC MAX phase material and iron–cobalt–chromite spinel coating/paint.

Which high-temperature materials contain molten tin?

The purpose of this paper is to evaluate three candidate high-temperature materials, possessing a range of thermal conductivities, for the containment of molten tin: graphite (C), silicon carbide (SiC), and mullite (Al 6 Si 2 O 13 ).

Can solar salt be a phase change material for high-temperature applications?

We propose solar salt as a phase change material for high-temperature applications due to its high energy storage capacity. To improve its thermal conductivity, varied carbon nanotube (CNT) concentrations were added to the salt using the ball-milling method. Thermal properties of composites were studied before and after 300 thermal cycles.

How does thermal energy storage improve the productivity of solar collectors?

Thermal energy storage improves the productivity of solar collectors. Phase change materials (PCM) are employed to store thermal energy in solar collectors, heat pumps, heat recovery, hot and cold storage. PCMs are encapsulated primarily in shell-and-tube, cylindrical, triplex-tube, spherical, rectangular, and trapezoidal containers.

Are PCM container designs practical for solar thermal storage?

PCM container geometry and orientations are practical passive heat transfer enhancement techniques in the long-term compared to adding nanoparticles and attaching fins. This review focuses on significant aspects of PCM container designs for practical solar thermal storage.
