“…Nevertheless, the challenge of designing and selecting compatible improvement methods that work synergistically has become increasingly complex [17][18][19][20]. For instance, challenges such as the extraordinary price of nanoparticles and their preparation, and technical difficulties associated with the design and manufacturing of TES systems that incorporate additional surface areas like permeable foams and fins [21][22][23][24]. Additionally, the incorporation of fins, permeable zone, or heat pipes may diminish free convection, thereby compromising the overall performance, as these elements occupy space that could otherwise be filled by PCM [25][26][27][28].…”

In pursuit of advancing the efficiency of cold energy storage, a uniquely designed curved container has been employed, filled with a water-nanoparticle mixtureQ. The container is equipped with fins, strategically leveraging the enhanced conduction facilitated by the presence of nanoparticles. The simulation of the intricate unsteady phenomena in this study has been conducted using the finite element technique, providing a robust analytical framework. The incorporation of an adaptive grid ensures a refined resolution, particularly in the vicinity of the ice front region. The nanoparticle fraction (ϕ) emerges as a pivotal factor directly influencing the rate of solidifying. The dispersion of nano-powders leads to a noteworthy reduction in completion time, demonstrating a substantial 33.21% improvement. The diameter of the nano-powders (dp) introduces diverse effects on the solidification process, primarily due to its significant influence on the conductivity of the nanomaterial. An in-depth exploration of the impact of dp reveals compelling insights. As the dp increases from its smallest size to 40 nm, there is a commendable 15.12% reduction in the required freezing time. However, a subsequent increment in dp beyond this threshold results in a notable 36.56% increase in the freezing time. The findings presented here not only contribute to the fundamental understanding of freezing processes but also hold practical implications for the design and optimization of cold storage systems.

“…Imperative treatment has been reported for such mode of heat transportation [8][9][10][11][12][13][14][15]. The nanoliquids are able to be demarcated as a colloidal combination of a basis liquid and nanoparticles which range from 1 to 100 nm [16][17][18][19][20][21][22]. Increased fraction of particles develops the thermo-physical topographies in the existence of basis liquid, that is, grows the heat conductivity of the liquid to grow the heating performance with an ecofriendly and low manner [23][24][25][26][27][28][29][30].…”

Adding additive with nano‐sized and considering porous media, new container has been generated and numerical technique was employed to model the convection process of cooling the four lobed surfaces which is situated inside three lobed tanks. Uniform flux was considered for four lobed surfaces while the outer surface is cold wall. With neglecting advection term due to employ of Darcy law, simpler form of momentum equations was appeared with is coupled with source term of magnetic field. Moreover, mixture model for testing fluid was applied with incorporating the efficacy of shape of nanopowders. Dispersing nanoparticles causes augmentation in Nu around 41.33% because of augmenting conductivity. The elevation of Ra makes Nu to increase around 38.98% in absence of Ha while this augmentation reaches to 1.54% in existence of Ha which means that domination of conduction in appearance of MHD. Augmenting shape parameter leads to rise of Nu around 11.72% while increment of Ha causes this function to reduce around 11.73%.
