“…109 Meanwhile, they possess the merits of high latent heat, chemical stability, non-corrosiveness and reusability. 110 Organic PCMs have been intensively used for TES applications, among which paraffin and fatty acids are the representative ones. Paraffin compounds typically comprise straight chain n -alkanes (CH 3 –(CH 2 ) n –CH 3 ), and their melting point and heat of fusion depend on the chain length.…”

A thermal energy storage system must integrate with a solar thermal collector for continuous energy delivery. This article focuses on the identification, preparation, thermo‐physical characteristic studies, and experimental investigation of a novel eutectic hot storage material for solar dryer applications. The identified organic novel eutectic mixture comprises stearyl alcohol and benzamide (SA‐B) with a molar ratio of 70:30. From the differential scanning calorimetry analysis, the melting point and enthalpy of the developed eutectic mixture were found to be 54. 26°C and 157.45 kJ kg−1 respectively. The melting temperature of the eutectic phase‐change material (PCM) fits the drying application. The corrosion analysis test confirms that the prepared eutectic mixture is compact with stainless steel (SS 316) heat exchanger material. Further, the eutectic PCM were characterized using Fourier transform infrared spectroscopy and thermo‐gravimetric analysis, which confirms the material is chemically and thermally stable. The thermal reliability of the eutectic PCM was evaluated through 1000 thermal charge and discharge cycling. In addition, the thermal conductivity of the identified material was found to be 0.18 W m−1 K−1. Thus, the specified material ascertained its suitability for thermal application. Further, 5 kg of eutectic PCM‐filled rectangular heat exchanger was integrated into the solar dryer. The use of eutectic PCM extended the drying time by more than 4 h, which can be helpful to run continuously on intermittent solar days and in the evening after sunset. Hence, the prepared eutectic SA‐B material is irresistible for hot storage dryer application.

“…Phase-change energy storage technology have been the topic of many investigations until recently since it has many industrial applications including aerospace, air conditioning and refrigeration, solar heat storage system, and building heating. A large number of literatures on both experimental and numerical studies were published in the past few decades (Farid et al, 2004;Rehman et al, 2019;Sharma et al, 2020). Ji et al (Ji et al, 2018) studied the phase change charging process in the latent heat energy storage device by setting the internal double fin length in the numerical method.…”

Detailed experimental investigation is presented for the heat transfer characteristics of an inclined shell-and-tube phase-change thermal energy storage unit. For the case of inclined angle α = π/4, the solid–liquid interface presented a concave surface because the heat transfer can be affected not only by conduction in the phase-change material (PCM) domain but also by natural convection significantly. The heat transfer rate increases with the increasing flow rate and inlet temperature of heat transfer fluid (HTF), but the flow rate of the HTF has little effect on the charging process for the case of qv ≥ 40 L/h. The heat transfer rate of PCM above the HTF tube increases with the increase of inclined angle. The effects of inclined angle on the heat transfer rate can be not negligible due to the obvious natural convection in the charging process.
