... for ocean exploration. Ocean thermal gradient is a permanent and reliable energy source that can be used to power UUVs using phase change material (PCM)-based thermal engines. When using PCM-based thermal engines to power UUVs, there are different energy conversion stages: thermal, hydraulic, kinetic...

.... The study deals with the SS under five different concentrations of salt (0, 5, 10, 20, and 35 g/kg). Previous experimental results reported in the literature indicate that the increase in salinity leads to a decrease in productivity, so phase change material (PCM) was added under the water basin to counter...

...Rajvikram Madurai Elavarasan; Preeti Singh; S. Leoponraj; Sourav Khanna; Mohanraj Chandran Maintaining the temperature of the photovoltaic (PV) panel within the described standard helps in achieving higher power conversion efficiency. To regulate the PV temperature, phase change material (PCM...

...Lokesh Kalapala; Jaya Krishna Devanuri One of the challenges in the design and development of a latent heat storage unit (LHSU) is to increase the charging and discharging rates which are inherently low because of low thermal conductivity of phase change materials (PCM). Out of various heat...

... synthesized. The developed samples were characterized uncycled and after 2000 thermal cycles. The results indicate that phase change material (PCM)/expanded perlite/graphene nano-platelets composite shows a significant increment in the thermal conductivity, reduction in the latent heat storage capacity...

... demands. There are several proven technologies for maintaining thermal comfort in buildings of which the use of phase change material (PCM) in buildings provides improved thermal comfort with fewer energy requirements. The present study analyzes the impact of the incorporation of PCM in roofs...

...Preeda Chantawong The author reports an experimental investigation of the thermal performance of a multipurpose photovoltanic (PV) solar wall with phase change material (PVSW-PCM). The PVSW-PCM configuration was made of double layers. The external layer consists of a 12 Wp photovoltaic panel...

...Hermes Chirino; Ben Xu Compared to solar photovoltaics, concentrated solar power (CSP) can store excessive solar thermal energy, extend the power generation, and levelize the mismatch between the demand and supply. Thermal energy storage (TES) system filled with phase change material (PCM) is a key...

... the two-phase heat transfer fluid poses a major challenge. A three-part storage system is proposed where a phase change material (PCM) storage will be deployed for the two-phase evaporation, while concrete storage will be used for storing sensible heat, i.e., for preheating of water and superheating...

...Yeliz Konuklu; Halime Ö. Paksoy In this study, a phase change material (PCM) sandwich panel was developed and tested to evaluate the resulting decrease in heating and cooling loads of a test cabin in Adana, Turkey, where Mediterranean climate prevails. The panel was formed by a macropackage...

...Wolf-Dieter Steinmann; Rainer Tamme Solar thermal systems, including direct steam generation in the absorbers, require isothermal energy storage systems. One option to fulfil this requirement is the application of phase change materials (PCMs) to absorb or release energy. The implementation of cost...
