Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
Thermal conductivity of 47 pairs of granitic rock specimens were measured using the Transient Plane Source (TPS) method. Crystalline rocks are being considered for the construction high-level radioactive waste (HLW) disposal systems. Dry and wet samples, the effect of water saturation, and the influence of temperature were all factors investigated in this study. ...
In this article, the transient plane source technique was used to determine the effect of iron, a flame retardant shape-stabilized phase change material (FSPCM), on the thermal conductivity of a sample of paraffin/high-density polyethylene (HDPE). With the results, it was determined that iron could be dispersed within the HDPE and paraffin samples, so as to improve the flame retardant efficiency. The results also concluded that the thermal conductivity of ...
This research proposed a new, flame retardant, shape-stabilized phase change material (PCM), for use in thermal energy storage. Typical paraffin and high-density polyethylene has great shape retention, however is highly flammable and has a low thermal conductivity. Researchers introduced expanded graphite and an intumescent flame retardant to the mix to improve the thermal properties and flammability, respectively. After several tests, including a thermal conductivity evaluation, on multiple variations of the ...
