Performance Assessment of Passive Fire Protection Materials

Three reference passive fire protection materials were tested to determine the effect that fire exposure has on their thermophysical properties. It was determined that the thermophysical properties during fire exposure have a significant impact on the performance of the materials. The knowledge of how the properties of these materials change upon exposure to fire will aid researchers in being able to better calculate the time to failure of the object ...

Chemical Composition, Density, Specific Gravity, Apparent Porosity, and Thermal Transport Properties of Volcanic Rocks in the Temperature Range 253 to 333 K

The density related properties (specific gravity, density, apparent porosity), and thermal transport properties were determined for diorite and granite rocks taken from the Shewa-Shahbaz Garhi volcanic complex, Pakistan. All measurements were made at varying temperatures from 253-333 K to determine the effect of temperature on the properties. It was found that all of the properties investigated depended on the chemical composition of the rock samples. For a given sample, the ...

Thermal conductivity improvement of composite carbon foams based on tannin-based disordered carbon matrix and graphite fillers

Composite carbon foams were prepared by mixing tannin-based resin with various graphite powders in an effort to improve the thermal conductivity relative to pristine carbon foams in order to use them as hosts for phase-change materials. It was found that using graphite powder with smaller particle sizes resulted in foams with a higher bulk density than those prepared with an equal amount of larger graphite particles, this increased density resulted ...

Online monitoring of wax deposition in sub-sea pipelines

The authors have performed a study to determine if heat pulse wax monitoring is capable of measuring the wax thickness build-up in an oil pipeline. A numerical model was developed to simulate the heat pulse equipment and to predict the wax thickness based on the experimental results....

Enhanced thermal and mechanical properties of epoxy composites filled with silver nanowires and nanoparticles

The authors have investigated the use of silver nanomaterials as a filler in epoxy resin in an effort to identify a composite resin with a high thermal conductivity for application as a thermal interface material. It was determined that the addition of silver nanoparticle and silver nanowires both increased the thermal conductivity of the resin, but the silver nanowires caused a much more drastic increase. It was found that by ...
