This dissertation is concerned with the utilization of mathematically architected Triply Periodic Minimal Surface (TPMS) based lattices for Latent Heat Thermal Energy Storage (LHTES) systems. With the advent of Additive Manufacturing (AM), TPMS structures can be readily manufactured. The objective of this dissertation was to investigate the heat transfer performance of TPMS structures vis-à-vis conventional metal foams represented by Kelvin cells while both were impregnated with a Phase Change Material (PCM). Numerical simulations were performed under various boundary conditions to assess the performance. It was found that TPMS structures outperformed conventional metal foam. Moreover, the effects of boundary conditions (isothermal and isoflux), configuration (sheet and solid TPMS), porosity, and functional grading on the performance of TPMS structures were studied. This dissertation reported the utilization of TPMS structures for LHTES systems for the first time in the literature. The superiority of TPMS structures makes them potential candidates for utilization in various applications related to LHTES.
