New Measurements of the Apparent Thermal Conductivity of Nanofluids and Investigation of Their Heat Transfer Capabilities

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 ...

Intercomparison of thermal conductivity measurements on an expanded glass granulate in a wide temperature range

This article aimed to compare the thermal conductivity of expanded glass granulate at high temperature ranges using a variety of steady state and transient testing methods (Guarded Hot Plate, Heat Flow Meter, Pipe Tester, Sphere, Hot Wire, Transient Hot Bridge). The thermal conductivity of the expanded glass granulates was determined from 170°C to 530°C with the different methods and apparatuses. The thermal conductivity was found to have increased from about 0.030 ...

Cellulose Nanocrystals reduce cold damage to reproductive buds in fruit crops

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 ...

A single-sided method based on transient plane source technique for thermal conductivity measurement of liquids

This article examined the effects of using the traditional vertical orientation method versus the single-sided horizontal method for transient thermal conductivity measurements of water, glycol, and methanol. It aimed to understand whether the single-sided horizontal method was effective at suppressing the onset of natural convection during the tests. From the analyses, it was seen that the proposed single-sided horizontal method can effectively suppress the onset of natural convection during the ...

Crystallization kinetics behavior of ionic liquid [EMIM][BF4] confined in mesoporous silica matrices

This study focused on the crystallization kinetics behavior of pure ionic liquid (IL) (1-ethyl-3-methylimidazolium tetrafluoro borate; EMIMBF4) as well as IL confined in mesoporous silica matrices (termed as ionogel). X-ray photoelectron spectroscopy (XPS) and transient plane source (TPS) measurements have been used to explain the slowing down of crystallization process of IL in confinement. Thermal conductivity of the IGs was measured using pellets of #IG2 and #IG3 with the ...
