Experimental investigation of dynamic melting in a tube-in-tank PCM system

Effectiveness of direct contact PCM thermal storage with a gas as the heat transfer fluid

“…Furthermore, an inert gas can be potentially more compatible with a larger range of PCMs, as the only impact on the chemical composition of the PCM is through evaporation, which in a closed system, is small. In addition, the direct contact process achieves a high level of mixing which can enhance the phase change cycling stability of the PCM [11]. Thongwik et al [12] experimentally investigated using carbon dioxide gas as the heat transfer fluid, with water as the PCM.…”

An overview on design methodologies for liquid–solid PCM storage systems

“…Recently, Tay et al [112] have investigated a new concept to improve the heat transfer during melting in tube-in-tank PCM systems, the dynamic melting. This method consists in creating melted paths in the frozen PCM using pre-melt tubes.…”

Heat transfer and thermal storage performance of an open thermosyphon type thermal storage unit with tubular phase change material canisters

“…Tay et al performed an experimental study of a typical indirect-contact type TSU which was a tube-in-tank system [4]. In this paper, a new concept of a heat transfer enhancement technique for a tube-in-tank phase change thermal energy storage system was investigated.…”
