Summary: The study developed a comprehensive electro-thermal model for cylindrical lithium-ion cells, showing that increasing the number of tabs connecting the jellyroll to the base can reduce internal thermal gradient by up to 25.41%. Side cooling was found to be more effective than base cooling at removing heat, with both methods resulting in similar thermal gradients within the cell.

Summary: This study reviews the current state-of-the-art self-heating methods and proposes the heating triangle as a new quantitative indicator for comparing self-heating methods. The heating triangle considers three fundamental metrics: specific heating rate, coefficient of performance, and specific temperature difference, enabling a quantitative assessment of self-heating methods. The analysis shows that similar metrics are observed for the same type of self-heating method, supporting the universality of the proposed indicator. The proposed heating triangle provides a standardized approach to compare heating methods and drive innovation.

Summary: The study found that increasing SOC of the battery leads to a longer time interval from voltage drop to the onset of thermal runaway. Additionally, the initial temperature of TR for LIBs at different SOCs is similar, but the temperature decreases as SOC increases.

Summary: This study selects Na2S2O3·5H2O (STP) and CH3COONa·3H2O (SAT) as supercooling salt hydrates to preheat lithium-ion batteries. The optimal design is to cover all sides of the battery with a salt hydrate thickness of 8.0 mm at 253.15 K, with heating rates of 0.236 K/s and 0.205 K/s for SAT and STP, respectively. However, as the ambient temperature increases to 273.15 K, the effective utilization of SAT and STP decreases, and a higher discharge rate provides higher effective utilization.

Summary: This study investigates the natural convection effects in the insulation layers of spherical storage tanks and their impact on the tanks' performance. The permeability and Rayleigh number of the insulation material are considered as key factors. The results show that as the Rayleigh number increases, new convective cells emerge and cause the cold boundary to approach the external hot boundary. In the case of large temperature differences, multiple solutions may coexist.

Summary: This paper investigates the two-phase flow and heat transfer characteristics of low-velocity jet impacting on a cylindrical surface. The study reveals that the heat transfer regimes are non-phase transition and nucleate boiling with the increase of heat transfer rate. The effects of jet impact height and outlet velocity on local surface temperatures are pronounced at the non-phase transition stage. The growth rates of heat transfer rate and liquid loss rate increase significantly from the non-phase transition to nucleate boiling stage.

The results reveal that the structures can influence the growth and removal of frost crystals, with the bottom grooves creating a frost-free zone and conical edges promoting higher frost crystal heights. Two effective methods for defrosting are observed: hand-lifting the groove and airfoil retraction contraction on protruding structures. This research provides valuable insights into frost formation and defrosting on millimeter-structured superhydrophobic surfaces, with potential applications in anti-frost engineering.

Summary: This study developed two thermal concentrators, one with a 2D design of uniform thickness and another with a 3D design, using the coordinate transformation technique and metamaterials. By structuring the thermal conductor, the desired local density-heat capacity product and anisotropic thermal conductivities were achieved. The homogenized thermal conductivities were obtained from finite element simulations and cylindrical symmetry consideration. A 3D concentrator was fabricated using 3D metal printing and characterized using a thermal camera. Compared to devices that solely consider anisotropic conductivities, the time evolution characteristics of the metadevice designed with coordinate transformation were closer to those of an ideal concentrator.

Summary: In this study, we investigated the supercritical heat transfer of CO2 in a horizontal tube with a diameter of 10.0 mm, covering a wide range of pressures, mass fluxes, and heat fluxes. The study revealed a non-monotonic increase in wall temperatures along the flow direction and observed both positive and negative wall temperature differences between the bottom and top tube. The findings were explained by the thermal conduction in the solid wall interacting with the stratified-wavy flow in the tube.
