Novel Multi-Objective Optimal Design of a Shell-and-Tube Latent Heat Thermal Energy Storage Device

In the present paper a new multi-objective optimisation procedure for design of shell-and-tube Latent Heat Thermal Energy Storage (LHTES) is proposed. A simple arrangement cylindrical shell with multiple vertical tubes has been examined. The considers, as variables, number tubes, tube internal radius and device height-to-diameter ratio, H/D, while storage volume kept constant. This analysis aims to detect set solutions which optimises LHTES performances evaluated in terms charging discharging times overall thermal energy capacity. To accomplish multi-objectives optimal design, simplified mathematical model employed. can evaluate prescribed given variables. proposed evaluates along most promising directions variables domain, leading significant improvement performances. Design Experiment, together Pareto dominance relationship, gives starting subset. permits enhance subset letting approach barrier. shows that, at end procedure, designer select on barrier best performance corresponding each chosen solution. will also allow maintaining low computational costs due only directions.
