摘要：
In the present paper, the charging process of a phase change material (PCM) in a novel heat exchanger called flat spiral tube heat exchanger (FSTH) is investigated for thermal storage purposes. The heat transfer fluid (HTF) flows inside the flat spiral tubes which are propagated throughout the shell. The so-called heat exchanger is examined considering various geometrical and operational boundary conditions. Variables such as a change in coil number of each flat spiral tube plane (FSTP), shell's tilt angle and the distribution of flat spiral tube planes throughout the shell along with HTF mass flow rate and HTF inlet temperature are investigated in this research numerically. Temperature, heat flux, the stored energy fraction, and liquid fraction contours along with PCM average temperature and melting procedure are examined in details. Simulation results indicate that the irregular distribution of FSTPs throughout the shell has a significant effect on the melting process and heat transfer procedure. Furthermore, vertical configurations are found to be more capable to store the PCM's energy in a specified duration of maximum solar radiation.
