Can lava rock be used as a heat storage material?

This study investigates the utilization of lava rock as a sensitive heat storage material in a double-pass solar air heater (DPSAH). The present study uses lava rock as a porous medium and material for sensible heat storage. The lava rock has never been used as a packed bed before in the literature.

Can lava rock be used as a heat storage double-pass solar air heater?

The present study used lava rock as the porous medium and sensitive heat storage double-pass solar air heater for thermal performance improvement. The experiment was performed on three sets of configurations: (i) DPSAH with no lava rock, C1-DPSAH, (ii) DPSAH with 50 % lava rock bed, C2-DPSAH, (iii) DPSAH with 100 % lava rock packed bed, C3-DPSAH.

Can lava rock be used as a solar air heater?

Lava rock's integration into the double-pass solar air heater significantly lowered the temperature of the absorber plate as compared to the conventional double-pass solar air heater, showcasing the thermal storage properties of the lava rock.

Why do lava rock heaters have a good thermal distribution?

It is because of the fact that output temperature is dropping and maintained at the same time by the lava rock. In contrast, the temperature of lava rock remains consistent throughout the charging and discharging process, making good thermal distribution in the heater. Fig. 12.

Why is lava a heat sink?

The greater volume of lava rock works as a heat sink, allowing for efficient heat storage, - transfer and extending contact between the airflow and the absorber plate. This extended interaction improves the heat exchange process, resulting in better heat transfer and, as a result, higher thermal efficiency.

What are the different thermal energy storage methods?

Under this paper, different thermal energy storage methods, heat transfer enhancement techniques, storage materials, heat transfer fluids, and geometrical configurations are discussed. A comparative assessment of various thermal energy storage methods is also presented.
