This article reports detailed investigation of using different Phase Change Materials (PCM) in various designs of Thermal Energy Storage (TES) Devices: specifically, heat exchanger. The focus is on the performance analysis of different types of heat exchangers acting as TES having various PCMs which are substantially reviewed in this paper. The study highlights the difference in their geometry and performance output. Further, the importance of different performance enhancement methods with parametric study of different heat exchangers using PCM is described. From the detailed investigation, finally, it is realised that the different factors such as no. of outer tubes, no. of inner tubes, tube material selected, type of PCM, provision of an extended surface, use of different metal foams and nanoparticles, various types of composites, charging and discharging characteristics and packed and cascaded units are different heat transfer enhancement methods to improve the heat transfer. A novel kind of heat exchanger known as Webbed tube heat exchanger using PCM is discussed for an efficient TES unit. Further, a review of quantitative analysis of melting time, solidification time, charging and discharging time is discussed.

“…Several techniques have been employed for improving the thermal behavior of PCM in direct contact heat accumulators, like the often-used extended fins 92 and the combination of PCM-graphite. 93 This kind of method accelerates the melting speed of solidified PCM from the thermal conductivity level, thereby accelerating the generation of HTF heat exchange channels. He et al 64 did related research, using the method of adding an inlet tube with flat fins and numerical simulation.…”

Phase change heat storage presents a promising solution to address challenges related to new energy intermittency and waste heat recovery. However, for it to function as an effective energy hub, heat storage becomes crucial. Among the available options, the direct contact heat accumulator stands out due to its simple structure, substantial heat transfer area, and minimal heat transfer resistance, making it a favorable choice for enhancing energy storage rates. Although a great deal of research has been done on phase change materials and heat accumulators over the years, a systematic review of direct‐contact heat accumulators is lacking. This article reviews the related research on direct contact heat storage, aiming to summarize the research work on direct contact phase change heat storage systems. Various phase change materials (PCMs) for direct contact systems are analyzed, and the study of PCM melting crystallization behavior, heat transfer coefficients and system performance in direct contact systems is summarized, as well as the improvement methods for direct contact vessels and PCMs. It provides a useful reference for future research on direct‐contact heat storage systems.

“…Studi visualisasi juga dilakukan namun hanya visualisasi aliran dengan sistem particle image velocimetry [11]. Bahan penyerap panas sebagai media dalam visualisi termal mempunyai karakterisik kapasitas panas (Cp dalam unit kJ/kg.K) yang tinggi seperti phase change material [12,13], etilen glikol [14], atau air [15].…”

Pada umumnya fenomena termal pada sistem alat penukar kalor tipe shell and tube dievaluasi menggunakan simulasi atau studi numerik. Padahal, karakteristik dari fenomena perpindahan panas konveksi-konduksi pada bagian dalam penukar kalor tipe shell and tube perlu divisualisasikan untuk menggambarkan fenomena sesungguhnya yang terjadi didalam strukturnya. Pada penelitian ini, visualisasi dari alat penukar kalor shell and tube dilakukan secara eksperimental. Alat penukar kalor shell and tube dipotong melintang untuk mengetahui profil distribusi termal melalui photothermal. Profil temperature hasil photothermal dibandingkan dengan hasil studi numerik. Perbedaan antara temperatur masuk shell dan masuk tube diset sebesar 30oC. Hasilnya menunjukan bahwa distribusi panas pada prototipe dan studi numerik mempunyai profil identik. Pengukuran perbedaan temperatur logaritmik menunjukan hasil antara studi eksperimental dan studi numerik memiliki selisih yang tidak signifikan.
