“…In recent years, the evolution of electromagnetic radiation sources has undergone exponential advancement that is re-ected in the increase in electromagnetic interference (EMI) shielding research, which is one of the key applications of magnetic nanoferrites. [1][2][3][4][5] The nanocrystalline ferrites have been a subject area of immense potential due to their profound applications in a wide range of interdisciplinary areas such as magnetic resonance imaging, drug delivery, magnetic hyperthermia treatment, spintronics, high-density memory devices, microwave devices, and power transformers. 2,[6][7][8][9][10] To achieve a higher gure of merit in these applications, the properties of magnetic nanoparticles (MNPs) need to be optimized for relevant applications.…”

“…There is often an imbalance in time or space between energy supply and energy demand in living and engineering applications [1][2][3]. For example, the energy load in urban areas varies more than 30% between day and night, which leads to lots of energy waste [4][5][6]. To fix these problems, thermal energy storage systems are attracting more attention [7][8][9].…”

“…Inspired by natural fractal geometry, Zhang et al [19] improved the energy-discharging rate, utilizing fractal fins for the latent heat device. The magnetic liquid could also significantly improve the heat transfer performance of the annular system with fins [4].

“…To weaken the NC, several attempts have been made [32], such as metal foam [33,34], multitube [35] and fins [36]. Internal and external fins were added on a latent energy storage unit by Pathak et al [4], and the NC was found to be effectively weakened. However, for the STIS device with longitudinal fins, it is still unclear which fin structure parameter is the most useful for weakening the NC.…”

The theoretical model of the solidification process of a shell-and-tube ice storage (STIS) device with longitudinal fins is established. The liquid fraction, the energy-discharging rate and the ice storage ratio are investigated, with particular focus on the effects of the fin structure parameters on the solidification process. Furthermore, the temperature and the streamline distributions are discussed to reveal the mechanism of the solidification process in the STIS device and the negative effect of natural convection (NC). It is indicated that the solidification process of the STIS device is dominated by the heat transfer via the fins at the beginning, and then by the heat transfer at the water-ice interface. The ice storage is negatively affected by the NC, for the reason that the water with a higher temperature stays in the lower part of the STIS device and the temperature gradient at the water-ice interface is small. The ice storage performance can be enhanced by increasing the fin structure parameters, including height, thickness and number.

The effective thermal management of electronic system holds the key to maximize their performance. The recent miniaturization trends require a cooling system with high heat flux capacity, localized cooling, and active control. Nanomagnetic fluids (NMFs) based cooling systems have the ability to meet the current demand of the cooling system for the miniaturized electronic system. However, the thermal characteristics of NMFs have a long way to go before the internal mechanisms are well understood. This review mainly focuses on the three aspects to establish a correlation between the thermal and rheological properties of the NMFs. First, the background, stability, and factors affecting the properties of the NMFs are discussed. Second, the ferrohydrodynamic equations are introduced for the NMFs to explain the rheological behavior and relaxation mechanism. Finally, different theoretical and experimental models are summarized that explain the thermal characteristics of the NMFs. Thermal characteristics of the NMFs are significantly affected by the morphology and composition of the magnetic nanoparticles (MNPs) in NMFs as well as the type of carrier liquids and surface functionalization that also influences the rheological properties. Thus, understanding the correlation between the thermal characteristics of the NMFs and rheological properties helps develop cooling systems with improved performance.
