This article studied the thermal conductivity values and measurements for the following two systems using the transient hot wire (THW) and transient plane source (TPS) techniques: ethylene glycol with added CuO, TiO2, or Al2O3 nanoparticles and water with added TiO2 or Al2O3 nanoparticles or multiwall carbon nanotubes (MWCNTs). A TPS technique using a thermal conductivity analyzer ...
This article studied a new asphalt pavement patch repair method that used dynamic infrared pre-heating. The thermophysical properties of the asphalt mixture were measured because they affect heat transfer and storage inside the pavement initiated by the absorbed radiation energy of radiative heat application on the surface of the pavement. One of these thermophysical properties, thermal conductivity, was measuring using the transient line source (TLS) method. From the TLS method, ...
Closed cell foams are widely used as protective garments in extreme environments. This article studied the use of neoprene-based materials in wetsuits by developing a strategy for reducing the thermal conductivity of a flexible, closed cell polychloropene foam. The thermal conductivities of the charged and unmodified neoprene foams were measured using the transient plane source (TPS) method with the TPS thermal conductivity meter. It was found that a wetsuit made ...
Cellulose nanocrystals (CNC) are renewable nano-biomaterials that may be suitable for reducing cold damage in fruit buds to their low thermal conductivity. This study was conducted to evaluate the potential of CNC as a thermal insulation material used in protecting sweet cherry and grape reproductive buds from cold damage. The thermal conductivity measurements were conducted using the transient plane source (TPS). It was found that the average thermal conductivity for ...
This article studied the flow and thermal transport characteristics of a ferrofluid based on transformer oil (Mogul Trafo CZ-A) and iron oxide nanoparticles. The thermal conductivity, specific heat, and thermal diffusivity were calculated using the transient plane source (TPS) method and a thermal constants analyzer was used for performing the measurements. It was found that the presence of the magnetic nanoparticles in the transformer oil (3%) increased its thermal conductivity by ...
