“…As the present study is carried out fully computational, initially the grid and validation along with time dependency were studied with the experimentally and numerically observed transient data by the Korawan et al [34] The simulated results show good agreement with the reported earlier data published as shown in Figure 3. Thus, a similar concept of the boundary was adopted in the present simulation.…”

ANSYS Fluent is used to simulate battery thermal management (BTM). A new concept design of cooling techniques with encapsulated phase‐change material (PCM) and internal coolant channels is proposed. In this study, the passive mode of cooling (MODEL‐A: without internal cooling) and proposed design incorporating with internal liquid channels (MODEL‐B, MODEL‐C, MODEL‐D, MODEL‐E, and MODEL‐F) are considered. The upper section of the chamber is the starting point for the melting progression, which then moves toward the downward lower section of the chamber. Two design concept cooling techniques are used: straight and spiral coolant channels. At the point 15 mm, the PCM gets initiated melting at 1000 s for MODEL‐A (no coolant channels), and only a heating up of PCM is observed for MODEL‐B and MODEL‐C. Faster initiation of melting period over and above 35 mm position and at higher position point 55 mm, which reaches a liquidus temperature 328.6 K at below 2000 and 1000 s, respectively. MODEL‐D, MODEL‐E, and MODEL‐F show the PCM temperature reduction across the axial length due to the presence of coolant channels. The spiral channels can maintain the liquid fraction for longer periods, which allows liquid to contribute to the sustainability of a longer‐lasting thermal storage system.

“…In addition, there is also another way to accelerate the time of melting without adding a surface area of the hot wall, that is by changing the shape of the model of tube-and-shell into a nozzle-andshell [10], the results show that melting time in the nozzle-and-shell model is 15.3% faster than the tube-and-shell model. Other research was carried out by changing the shape of the tubeand-shell into combine-and-shell [11]. The result showed that the melting time in the combineand-shell model was 40% faster than the tube-and-shell model.…”

Paraffin as a heat storage material has many advantages but also has drawbacks, namely low thermal conductivity so that the melting time becomes long. Efforts have been made to accelerate the melting time, including by increasing a surface area of the hot wall, or also by changing the geometry. In this study was carried out by changing the temperature of the hot wall from uniform to increase gradually, uniform hot wall temperature was 330 K, increased gradually hot wall temperature was 324 K, 327 K, 330 K, 333 K, dan 336 K. Paraffin used has specifications according to reference. They have performed numerically used ANSYS software. They are using three models, namely modelA, model-B, and model-C. The study aimed to obtain liquid-solid interface contours, changes in temperature at measurement points, and changes in the liquid fraction. The results of model validation show similarities to previous studies. The results show that the melting time in the model-A is the fastest, followed by model-B and model-C.

A comprehensive review of heat transfer intensification methods for latent heat storage units

et al. 2020

View full text Add to dashboard Cite

Latent heat thermal energy storage (LHTES) systems and their applications have been very substantive for the developments in energy science and engineering. The efficiency of LHTES systems largely depends on the thermal conductivity of the phase change materials (PCMs) and the heat transfer mechanisms in them. This review focuses on the methods employed to enhance heat transfer in LHTES systems which accordingly improve their storage performance. This includes the possible geometrical configurations of LHTES systems and the effects of their design parameters. The various methods adopted for enhancing LHTES systems' performance through either applying nanomaterials additives, using cascaded or encapsulated PCMs, or employing extended surfaces, such as fins, are discussed in detail. Additionally, various designs of PCM based heat exchangers with active and passive heat transfer techniques were highlighted. These systems are critically analyzed to help selecting reliable techniques and compatible materials for effective designs in order to achieve more efficient LHTES systems. This review would be helpful for the researchers to further develop heat transfer intensification mechanisms in LHTES systems.
