“…The phase‐transition of the PCM was solved with the enthalpy‐porosity approach, and the melting and solidifying processes was simulated with the melting and solidification model. The natural convection and thermal radiation that occurred within the CPCM are neglected due to confinement of the PCM in the interparticle voids of the EG/PCM composite .…”

Summary This article reports a recent study on a liquid cooling‐based battery thermal management system (BTMS) with a composite phase change material (CPCM). Both copper foam and expanded graphite were considered as the structural materials for the CPCM. The thermal behaviour of a lithium‐ion battery was experimental investigated first under different charge/discharge rates. A two‐dimensional model was then developed to examine the performance of the BTMS. For the copper foam‐based CPCM modelling, an enthalpy‐porosity approach was applied. The numerical modelling aimed to study the impacts of CPCM types and inlet velocity of heat transfer fluid on both the maximum battery temperature and temperature distribution under different current rates. Dimensional analyses of the results were performed, leading to the establishment of relationships of the Nusselt numbers and dimensionless temperature against the Fourier and Stefan numbers.

“…This means that PCMs' properties should be adjusted with regard to both daily and monthly variations of the ambient air temperature at the particular location. Moreover, other problems related to the application of PCMs into the building structure have to be solved, eg, modification of material properties, development of methods of incorporation of these materials into the structure of the building, or enhancement of heat transfer rate between the heat transfer medium and PCM …”

“…Moreover, other problems related to the application of PCMs into the building structure have to be solved, eg, modification of material properties, 6,10,11 development of methods of incorporation of these materials into the structure of the building, 7,[12][13][14] or enhancement of heat transfer rate between the heat transfer medium and PCM. [15][16][17][18] The determination of the optimal characteristics of the PCM, which is to be used in a given system, requires an analysis of heat transfer process in the TES unit during the whole cycle, ie, during its charging and discharging, with variations of local climatic conditions included not only for one or several days but also for the whole summer season. In the paper, such a study for the TES system integrated with the ventilation system of the building 19 and operating during the summer, ie, during May, June, July, August, and September in Central Poland, is presented.…”

Summary The thermal energy storage unit in the form of the ceiling panel made of the gypsum‐microencapsulated phase change material composite with internal U‐shaped channels was optimised applying previously developed 1D‐3D numerical simulator. Calculations were carried out for variable inlet velocities of air, different properties of the composite expressed by enthalpy‐temperature curves, and summer climatic conditions in Central Poland (Warsaw). Optimal working temperature ranges of the composite were determined. Moreover, studies showed that for Central Poland, composites with wide ranges of the working temperature are preferred due to significant daily variations of ambient temperature during the whole summer.

“…So, investigations on performance enhancement method for LHS process are urgent to be carried out. Generally speaking, there are three kinds of enhancement methods: (1) enhance PCM thermal performance, for example using some high thermal conductivity additives to form CPCM [13][14][15], (2) transfer surface, such as using enhanced heat transfer tubes [16][17][18], (3) enhance uniformity of heat transfer process, such as using multistage PCMs [19][20][21].…”
