Magneto‐Hydrothermal and Entropy Analysis of Double‐Diffusive Convection in a Nano‐Encapsulated PCM‐Suspended Elliptical Pipes Thermal Storage Tank: Impact of Exothermic Reaction

Energy Science &Engineering, Volume 13, Issue 12, Page 5882-5909, December 2025.
ABSTRACT PCMs store thermal energy during phase transitions without temperature changes, making them valuable for various thermal applications. When direct PCM use isn't practical, researchers have developed encapsulation methods as an alternative approach.
