Special Issue Information

Dear Colleagues,

Heat transfer phenomena take place in many natural and industrial applications and at different scales. Our understanding of the underlying physics behind heat transfer phenomena in different applications is very important to enrich our overall scientific knowledge.

Heat transfer is almost present everywhere, including in many engineering applications, such as chemical, aeronautical, mechanical, civil, environmental, biomechanical, aerospace, process, petroleum, and production engineering.

This Special Issue focus on heat transfer theoretical and applied research including, but not limited to, analytical developments, advanced computational modeling and simulations, and experimental measurements techniques.

This Special Issue focuses on heat transfer in engineering applications including, but not limited to: solar collectors, advanced multiphase, porous and phase-change materials for enhanced heat transfer, advanced cooling of electronic equipment, advanced cooling of nuclear reactors, multidisciplinary design and optimization of heat transfer equipment and thermal systems, urban and district heating, cooling of subways and transportation systems, advanced cooling of electric batteries and electric motors, coupled heat and mass transfer in reactive flows, design and optimization of multifunctional heat exchangers, reactors and mixers,  energy conservation in buildings, thermal energy storage and conversion.

Tetrabutylammonium bromide (TBAB) is considered a promising alternative cold energy storage material. Due to the high dissociation heat of phase transition at an atmospheric pressure of 278–293 K, which reaches 200–500 kJ/kg, this substance is considered an effective cold energy storage medium for air conditioning systems. In this paper, the cold storage crystallization process of TBAB solution with different concentrations was tested by conducting experiments and the phase transition’s temperature and latent heat were measured. Finally, the growth characteristics of TBAB hydrate crystals with different concentrations (10%, 20%, 30% and 40%) were analyzed. Considering the cold storage temperature, phase transformation temperature and latent heat, the cold storage effect is the best when 40% TBAB solution is used. Although single substance phase change materials have a long service life, they have problems with low thermal conductivity and high undercooling. Therefore, researchers usually improve the performance of phase change materials by adding other auxiliary materials, thereby enhancing their application prospects. Among these auxiliary materials, adding nano additives to phase change materials can significantly improve latent heat, thermal conductivity and nucleation ability, while also reducing undercooling. Therefore, we studied the influence of different nano-additives (Al2O3, SiC, TiO2 and ZnO) on phase change materials. The composites with excellent properties were screened by cooling step cooling curve and differential scanning calorimeter (DSC). Compared with pure TBAB solution, the phase transition latent heat of the composite phase change materials (PCMs) prepared by adding nanoparticles were significantly increased. The results show that adding nano-SiC into 40% TBAB solution can obtain better performance. This work not only provides reference for the further research, but also a sight to design the phase change materials for the application of new phase change cold storage materials. Full article

This particular study focuses on investigating the heat and mass transport characteristics of a liquid flow across the conical gap (CG) of a cone-disk apparatus (CDA). The cone and disk may be taken as stationary or rotating at varying angular velocities. Consideration is given to heat transport affected by solar radiation. The Rosseland approximation is used for heat radiation calculations in the current work. To observe the mass deposition variation on the surface, the effect of thermophoresis is taken into account. Appropriate similarity transformations are used to convert the three-dimensional boundary-layer governing partial differential equations (PDEs) into a nonlinear ordinary differential equations (ODEs) system. Particularly for the flow, thermal and concentration profiles, plots are provided and examined. Results reveal that the flow field upsurges significantly with upward values of Reynolds numbers for both cone and disk rotations. The increase in values of the radiation parameter improves heat transport. Moreover, it is detected that the stationary cone and rotating disk model shows improved heat transport for an increase in the values of the radiation parameter. Full article
