The circular shell had an inner diameter of 90 mm and a length of 120 mm. Two nested copper tubes, with diameters of 9 mm and 19.05 mm, were concentrically placed to transfer heat from the HTF (heat transfer fluid) to the PCM. As depicted in Fig. 3, hot water enters the system through the inner tube at the inlet of the HX.. Upon reaching the end, it …

The primary advantage of LHTES is its ability to store (charging) and release (discharging) of thermal energy at near-isothermal conditions and high energy density. In general, the TES system consists of heat storage medium, Heat transfer fluid (HTF) and containment unit (shell). For LHTES unit, thermal energy is stored in phase …
Core-shell structured nanomaterials are suitable for photosensitization due to the unique core-shell structure and high emission and adsorption spectra. Various core-shell structured nanomaterials, including CdS, [ 224] PbS, [ 225, 226] CdTe, [ 227] ZnSe, [ 228] and Ag 2 S, [ 229] etc, have been investigated in QDSSCs.
The physical model of the present work is a horizontal shell and tube latent heat thermal energy storage unit. The PCM is placed in the shell side while the HTF streams in the copper inner tubes as displayed in Fig. 1 (a) the outer shell and the inner tube diameters are 88 mm and 12.7 mm, respectively, which are chosen from Mehta et al. [13] …
