Abstract
Analytical considerations were presented for the solidification process of latent thermal energy storage capsules. The arrangement of the capsules was in alignment with the flow direction. It was shown that good agreement between the predicted and the experimental results can be obtained by application of the quasisteady assumption on the solidification process. Numerical calculations for fifty rows of capsules showed that there is a certain location in the rows where the heat transfer rate between the capsules and the flow shows a maximum value, and the location moves to the down-stream rows as time proceeds.
