Multi-objective sensitivity analysis of shell-and-tube LHTES performance

In the present paper a sensitivity analysis has been carried out concerning charging/discharging time and stored energy performances of shell-and-tube LHTES with respect to number tubes tube internal radius. The aim this is investigate how design variables affect performance. could lead determine thermal storage optimal design. Thus, key role in selection several acceptable solutions. considered exhibits cylindrical shell geometry characterized by constant height diameter. This aspect allowed employ simplified theoretical models able predict These consider heat exchange wall temperature whereas area whole PCM volume vary according variables. represents first step solve multi-objective optimization problem then best solutions both performance domains.
