Enhanced heat transfer in a PCM shell-and-tube thermal energy storage …

The PCM thickness was determined by the shell-to-tube diameter ratio. In work by Kalapala and Devanuri [24], values from 3.5 to 4 were reported to be the best ratio to obtain maximum energy storage density and short melting time. The shell-to-tube ratio for M01, M02, M03, M05, and M08 was constant and equal to 3.47.
