A thermal energy storage (TES) equipment utilizing phase change material (PCM) was designed and built. The PCM is sealed inside metal tubes and exchanges heat with process fluid flowing outside. The storage capacity characteristics of the system was analyzed based on date covering the inlet and outlet temperatures of the process fluid, volumetric flow rate of the process fluid, and temperature ...

| In this paper, recent progress of phase change memory (PCM) is reviewed. The electrical and thermal properties of phase change materials are surveyed with a focus on the scalability of the materials and their impact on device design. Innovations in the device structure, memory cell selector, and strategies for achieving multibit operation and 3-D, multilayer high-density memory arrays are des...

Phase Change Memory (PCM) has better scalability and smaller cell size comparing to DRAM. However, further scaling PCM cell in deep sub-micron regime results in significant thermal based write disturbance. Naively allocating large inter-cell space increases cell size from ideal 4F 2 to 12F 2. While a recent work mitigates write disturbance along word-lines through disturbance resilient data enc...

Phase change materials are a promising strategy to reduce energy consumption in a wide range of applications including the building sector. Many studies have been done to evaluate the impact of PCM on thermal properties of building materials, however there exists little information on the influence of PCM on other properties of the support materials. This knowledge is necessary to determine the...

This paper presents experimental results that can be applied to select a possible phase change material (PCM), such as a latent heat material (LHM), to control the hydration heat in mass concrete structures. Five experimental tests (microconduction, simplified adiabatic temperature rise, heat, and compressive strength tests) were conducted to select the most desirable LHM out of seven types of ...

many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

We report a distributed loaded line phase shifter based on a new class of electro-thermally actuated RF MEMS devices using paraffin phase-change material (PCM). Paraffin is a low loss (tan δ = 6.6×10−4) mechanical phase-change material that exhibits a 15% volumetric change through its solid-liquid transition. Due to its unique electrical and mechanical properties, paraffin PCM variable capacito...

This study develops a novel composite phase change material (PCM) based onparaffin/hydrophobic expanded perlite and exfoliated graphene nanoplatelets as heat transferpromoter.

The micro-morphology characteristics of composite PCM s...

The selection and configuration of building materials for optimal energy efficiency in a building require some assumptions and models for the thermal behavior of the utilized materials. Although the models for many materials can be considered acceptable for simulation and calculation purposes, the work for modeling the real time behavior of phase change materials is still under development. The...
