In this effort, we evaluated the device performance for a range of design variables (fin pitch, fin length, tube diameter, etc.) and selected the design with the largest energy density for a 1-h discharge. In this analysis we found that larger fin spacings (∼6 mm) were preferable, ...
13.2.2.2 Latent heat storage The latent heat storage (LHS) uses phase change materials, such as wax, and salt hydrates, as the storage medium, whereby energy is absorbed or released when a change of phase occurs at a specific temperature. The latent heat storage system's output can be modi...
