Phase change material (PCM) is an effective thermal management method to improve the thermoelectric conversion performance of a system. PCM can not only absorb excessive energy at high temperature protect module (TEM) and increase maximum available range, but also compensate for intermittent extend working time TEM. In paper, transient improved by adding traditional generator (TEG) Due low cond...

We describe a self-referencing interferometer in which the wavefront and its complex conjugate are generated in a Fabry-Perot cavity having one phase conjugate mirror (PCM). The finite response time of the PCM allows one to display momentarily the moiré between old and new interferograms after a sudden change has affected the input wavefront. Results using an externally pumped BaTiO(3) crystal ...

With latent heat thermal energy storages, can be stored at a constant temperature level with high storage density using the enthalpy of solid-liquid phase change material. During discharge process storage, material (PCM) solidifies transfer surface and increases resistance. This decreases transferred power time state charge. The rotating drum exchanger, experimentally investigated in detail for...

Capacitive coupling and direct shuttling of charges in nanoscale plasmonic components across a dielectric spacer and through a conductive junction lead to excitation of significantly different dipolar and charge transfer plasmon (CTP) resonances, respectively. Here, we demonstrate the excitation of dipolar and CTP resonant modes in metallic nanodimers bridged by phase-change material (PCM) sect...

A new type of lightweight plaster with the thermal capacity enhanced by PCM (Phase Change Material) addition is analyzed. The basic physical characteristics, namely the bulk density, matrix density, total open porosity, and pore size distribution are measured at first. For description of mechanical properties, compressive strength measurements are done. The thermal properties are characterized ...

This paper discusses the possibility of increasing the energy performance of thermal brick through integration with two different technologies: the first is based on the insertion of phase change material (PCM) inside the enclosures of the bricks, while the second involves covering the internal surface of the enclosures with low emissivity coating. PCM was employed to increase the thermal mass ...

The present paper is confined to the discussion of technical grade paraffin waxes as phase change material (PCM) for cool storage and the cool storage systems capital cost investment. The objective of this study is to determine the potential for using cool storage systems. The thermal properties of technical grade paraffin waxes as PCM are investigated, and static and dynamic cool storage proce...

A central issue of nanoelectronics concerns their fundamental scaling limits, that is, the smallest and most energy-efficient devices that can function reliably. Unlike charge-based electronics that are prone to leakage at nanoscale dimensions, memory devices based on phase change materials (PCMs) are more scalable, storing digital information as the crystalline or amorphous state of a material...

Porous latent heat thermal energy storage for thermoelectric cooling is simulated via a matrix-based enthalpy formulation, having the temperature as unknown, in a three-dimensional domain. The system is made up of two aluminum containers; the inner one contains the cooling objective in water suspension and the outer one the phase change material (PCM) in a porous aluminum matrix. The system’s c...

This paper focuses on the melting of phase change material capsulated in elliptical cross-section horizontal cylinder under convective boundary conditions. Different parameters are discussed, namely, HTF inlet temperature and velocity axes ratio capsule cross-section. The effect temperature, velocity, was studied using CFD software FLUENT 6.3.26. A comparison between numerical experimental resu...
