Abstract The evacuated-tube collector (ETC) for solar heat production is one of the most efficient systems to convert Sun energy into usable energy. Unfortunately, some technological barriers are still present in solar-thermal that limit use these technologies decarbonize processes. An important obstacle requirement at stable temperatures, which not always achievable by fields, e.g. variable sk...

Improved thermal storage capacity and reduced building energy consumption can be attained by utilizing phase-change materials (PCM) in glass enclosure structures, which effectively utilize solar to improve the building’s performance. This article investigates performance of double-layer filled with PCM as a function relevant physical parameters. Numerical analyses were conducted on units assess...

Spatial alignment is an essential step before any further processing (such as fusion and change detection) of multiframe images can be done. We present a new algorithm that aligns translated and rotated pair of 3D images by means of phase correlation method (PCM). PCM is a computationally efficient method for translation estimation. We generalize a known polar-mapping approach of 2D image regis...

To overcome the weak thermal conduction of phase change materials (PCM), This investigation aims to study effect circular Y-shaped fins added a two-pipe latent heat-saving unit compared with conventional fins. The system is placed in straight-up orientation, and PCM located annulus, whereas hot water moved inside internal tube charge material (PCM) point 35°C. Different independent geometric fa...

Although phase-change materials (PCMs) have been studied for more than 50 years, temperature-dependent characterization of the phase transition dynamics remains challenging due to lack nanosecond-nanoscale thermometry. In this article, we utilize four-terminal, indirectly heated switch (IPCS), which was originally designed nonvolatile radio frequency (RF) applications, as an ultrafast electroth...

Abstract Phase change materials (PCMs) applied to photovoltaic (PV) panels are a promising solution recover the large share of energy from incident radiation, not converted into electricity. PCMs can store huge amount energy, exploiting solid-liquid phase change, which occurs at nearly constant temperature. In addition, reducing temperature PV panel increases its electric conversion efficiency....

Phase-change materials (PCM) play off their advantages over conventional heat storage media when used within narrow temperature ranges. Many cooling and buffering applications, such as cold battery cooling, are operated small differences, therefore, they well-suited for the application of these promising materials. In this study, capacities different phase-change material emulsions analysed und...
