Thermal characteristics on melting/solidification of low temperature PCM balls packed bed with air charging/discharging

© 2019 The Authors. Melting and solidification phenomena of low-temperature phase change material (PCM) balls packed bed with air flowing during charging and discharging were tested and modeled by numerical enthalpy method. In this study, a commercial paraffin RT-42 (melting point 38°C-43°C) contain...

It could be found that the simulated results on the PCM temperature and the outlet air temperature of the PCM bed agreed well with those of the experimental data. With these data, correlations were developed in dimensionless terms which could be used to estimate the air temperature leaving the bed at any operating period and any PCM bed thickness for both melting and solidification processes. 2019-08-05T04:33:33Z 2019-08-05T04:33:33Z 2019-09-01 Journal 2214157X 2-s2.0-85063522684 10.1016/j.csite.2019.100431 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85063522684&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/65450
