Intensifying the thermal response of PCM via fin-assisted foam strips in the shell-and-tube heat storage system

Jasim M. Mahdi et al.

Summary: The paper proposes a method for intensifying the thermal response of phase-change materials (PCMs) in the shell-and-tube containment system by applying fin-assisted foam strips. It suggests using foam strips instead of full foam to achieve better enhancement rate in a more convection-friendly environment. Experimental results show that uneven fins with foam strips have the best enhancement potential compared to other additives in use, with melting rate enhancement up to 58 % and solidification rate enhancement up to 42 % depending on the type and volume fraction of the enhancement additive used.

Melting Enhancement in a Triple-Tube Latent Heat Storage System with Sloped Fins

Mustafa Z. Mahmoud et al.

Summary: This study presents a numerical optimization of PCM heat exchangers with circular fins of different orientations and distributions to enhance melting and heating rates. Results show that adopting downward-upward fin orientations, longer but thinner fins, and appropriate combinations of Reynolds numbers and inlet temperatures can significantly increase the potential for enhancing PCM melting.

Soroush Entezari et al.

Summary: This study introduces a novel triplex-tube helical-coil thermal energy storage unit and utilizes numerical simulations to assess its performance, showing a significant reduction in melting time compared to conventional units. A tilt angle of 0 degrees demonstrates the best performance, and the addition of Al2O3 nanoparticles to PCM proves to be the most effective in reducing melting time.
