Energy storage square tube

How does a triangular tube improve energy storage/release capacity?

Energy storage/release capacity improved by 0.15 % to 12 % with the triangular tube. Phase change materials (PCMs) play a critical role in energy storage systems due to their high latent heat capacity, enabling efficient thermal energy storage and release during phase transitions.

Which multi-tube lhes has the highest energy storage/release capacity?

Multi-tube LHES with various geometries using metal foam-enhanced PCM is analyzed. The triangular tube achieved the highest reduction in charge time at 10.4 %. The square tube achieved the highest reduction in discharge time at 27.8 %. The triple triangle tube provided the greatest energy storage/release capacities.

Does tube geometry affect multi-tube energy storage enhanced with metal foam?

In the presented study, the interaction between the number of tubes and tube geometry in multi-tube energy storage enhanced with metal foam was investigated in terms of charge/discharge time, temperature change, and heat storage/release capacity. The main conclusions obtained are given below:

Does number of tubes affect energy storage and release capacity?

The energy storage and release capacity during melting and solidification processes did not increase proportionally with the number of tubes. In the quadruple-tube model, heat energy was distributed more uniformly within the PCM container.

How does a triple-triangle tube increase energy storage capacity?

Compared to other single- and multi-tube designs, the increase in energy storage capacity with the triple-triangle tube ranged from 0.41 % to 12 % The solidification of the liquid PCM started at the tube surface, leading to the loss of contact between the tube and the liquid PCM.

Are square tubes better than circle tubes in solidification process?

However, the lowest discharge times were obtained for square-tube configurations in the solidification process and the discharge time was decreased by 13.6 % to 27.8 % compared to circle-tube designs. The energy storage and release capacity during melting and solidification processes did not increase proportionally with the number of tubes.
