Thermal And Structural Characterization Of Macro-Encapsulated Phase Change Material Integrated Into Concrete Cubes, Yasir Rashid Apr 2018

Thermal And Structural Characterization Of Macro-Encapsulated Phase Change Material Integrated Into Concrete Cubes, Yasir Rashid

Theses

High-energy consumption in buildings is a research issue of great importance today, with solid-liquid phase change materials (PCMs) proving an excellent candidate for passive means to reduce energy consumption. In the current research, a novel protective coating was developed from geopolymer to encapsulate a PCM to prevent leakage in the liquidous phase. The PCM was characterized using a customized temperature history method (THM) and standard differential scanning calorimetry (DSC). Two different porous materials, polyurethane foam and lightweight expanded clay aggregate (LECA), were selected to hold the PCM and act as a matrix in which to develop PCM capsules. Ingredients of …


Numerical Validation Of Cooling Performance Of Phase Change Materials Integrated Into Heat Sinks For Electronics Cooling, Shaimaa Mohamed Abu Ayyan Dec 2015

Numerical Validation Of Cooling Performance Of Phase Change Materials Integrated Into Heat Sinks For Electronics Cooling, Shaimaa Mohamed Abu Ayyan

Theses

This study aims to analyze the cooling performance of phase change materials (PCMs) integrated into metallic heat sinks (HSs) both experimentally and numerically. For the experimental part of the study, a test setup has been constructed to test PCM integrated heat sinks. The heat sinks are prepared as metallic containments having fins with fixed inter-fin spacing. The volume between the heat sink fins is filled with PCM namely: a paraffin wax, salt hydrate-calcium chloride and milk-fat, then the whole system is sealed for testing under various heat loads at 4W, 6W, 8W and 10W. Four modes of operation are experimentally …
