Abstract Phase change materials (PCM) are wildly investigated and used in the fields of thermal energy storage control electronics. Numerical simulation is an important method research, development, analysis design PCM based systems. At present, there two main numerical methods for solid-liquid phase transition problems with natural convection: finite volume (FVM) on macroscopic scale continuit...

In recent years, the energy consumption of computing systems has increased and a large fraction of this energy is consumed in main memory. Towards this, researchers have proposed use of non-volatile memory, such as phase change memory (PCM), which has low read latency and power; and nearly zero leakage power. However, the write latency and power of PCM are very high and this, along with limited...

The use of the latent heat of phase change materials (PCM) is considered a promising approach to store heat at a nearly constant temperature for direct steam generation (DSG), but the poor thermal conductivity of commonly available storage materials imposes severe limitations on storage performance. A new method is proposed to overcome the limitations of the low thermal conductivity. The approa...

The coupled transport of heat and electrical current, or thermoelectric phenomena, can strongly influence the temperature distribution and figures of merit for phase-change memory (PCM). This paper simulates PCM devices with careful attention to thermoelectric transport and the resulting impact on programming current during the reset operation. The electrothermal simulations consider Thomson he...

The present paper numerically analyzes a passive cooling system using enclosures with different geometries filled with thermal conductivity-enhanced phase change material (PCM). A numerical code is developed using an unstructured finite-volume method and an enthalpy-porosity technique to solve for natural convection coupled to a solid-liquid phase change. Five geometries containing the same vol...

The need to reduce the use of fossil energy, which is running out and harmful environment, in response increasing energy demand with rapid urbanization, population growth developing technologies reveals necessity research application using renewable energy. Phase-change materials (PCM) are one most suitable methods for efficient thermal originating from clean sustainable sources. PCMs play impo...

We investigate the dynamic thermal performance of a molten-salt packed-bed thermal energy storage (TES) system using capsules filled with high-temperature phase change material (PCM), which is identified as a promising low-cost TES system for concentrating solar power (CSP) plants. A transient twodimensional dispersion-concentric (D-C) model is modified to account for the phase change process w...

Climate change is leading construction engineers and building stakeholders to improve materials thermal insulation heat storage capacity. The development of energy efficient with a low environmental impact real challenge. In this sense, earth-based are known worldwide have been used since thousands years.

Phase change memory (PCM) is an emerging memory technology with many attractive features: it is non-volatile, byte-addressable, 2–4X denser than DRAM, and orders of magnitude better than NAND Flash in read latency, write latency, and write endurance. In the near future, PCM is expected to become a common component of the memory/storage hierarchy for a wide range of computer systems. In this pap...
