Optimization of capsule diameters in cascade packed-bed thermal energy

The packed-bed thermal energy storage system (PBTES) has broad application prospects in renewable energy, such as for solar, hydraulics, biomass, and geothermal. This study varied the capsule diameter arrangement of the PBTES using a genetic algorithm (GA) to optimize the thermal performance of the cascaded three-layer PBTES during charging.

Melting behavior of an organic phase change material in a square

A numerical analysis of melting of an organic phase change material (PCM) in a square thermal energy storage (TES) capsule with an array of high voltage wire electrodes has been performed. Fully coupled set of governing equations for fluid flow, heat transfer, phase change, electric field and charge transport are solved using the opensource

The Effect of PCM Capsule Material on the Thermal Energy Storage

Initially, the energy is stored inside the capsules as sensible heat until the PCM reaches its melting temperature. As the charging process proceeds, energy storage is achieved by melting the PCM at a constant temperature. Finally, the PCM becomes superheated. The energy is then stored as sensible heat in liquid PCM.

The energy storage capacity for the 100 mm capsule is 85.35 % higher than that of the 50 mm capsule and 42.06 % higher than that of the 75 mm capsule. At a bath temperature of −9 °C, the energy stored increases by 91.13 % compared to the 50 mm capsule and by 45.90 % compared to the 75 mm capsule.

Heat transfer characteristics of the latent heat thermal energy storage

Basic experiments were carried out to simulate a solar energy storage capsule, using a horizontal cylindrical capsule (300 mm length, 40 mm o.d.) filled with naphthalene as the phase change material. The variation of heat flux during the processes of heat storage and removal was measured by a heat flow meter wrapped around the capsule, as the

Photothermal Energy‐Storage Capsule with Sustainable

Herein, a photothermal energy-storage capsule (PESC) by leveraging both the solar-to-thermal conversion and energy-storage capability is proposed for efficient anti-/deicing. Under illumination, the surface temperature can rise to 55 °C, which endows fast droplet evaporation to prevent the subsequent bulk freezing, and the accumulated ice and

Performance enhancement of ice storage capsules by biomimetic

The cooling energy storage capacity of each capsule is compared in Fig. 10. Apparently, pure water without fin has the highest capacity of cooling energy storage which is 322.8 kJ∙kg −1 under the condition of T i = 276.15 K, T c = 268.15 K. With the addition of fin-Ⅰ and fin-Ⅱ series, approximately 0.9% ∼ 1% storage capacity is lost.

Nickel-rich layered oxide stands as one of the most promising cathodes in demand for higher energy density of lithium-ion batteries (LIBs) in next generation. While increasing nickel content brings more capacity, it also makes this kind of cathode more vulnerable to the ambient, both the air outside the cell and the electrolyte inside, causing aggravated storage, structural and
