P. Mavros et al., STRATIFIED ENERGY-STORAGE VESSELS - CHARACTERIZATION OF PERFORMANCE AND MODELING OF MIXING BEHAVIOR, Solar energy, 52(4), 1994, pp. 327-336
The performance of several solar energy storage vessels is extensively
tested and recorded according to the CSTG procedure and their efficie
ncies in energy delivering is calculated. The stratification inside th
e vessels is determined by matching the profiles to predictions from a
layers-in-series model. The model is extended to account for dead spa
ces inside the vessel and is proven to be useful in evaluating the per
formance of stratified solar energy storage vessels.
