**2.1 Fundamental studies related to cold thermal storage**

Ice on tube system essentially consists of cold pipes submersed in stagnant water or cold pipes submersed in a cross flow of water. Freezing of water was studied by several researchers. **Table 2** shows a summary of the works that have been done by several researchers to study the freezing phenomena as well as melting.
