Glass components recovered from dismantled cathode ray tubes (CRTs) are very difficult to recycle or reuse and so other methods of using these glass components must be found to prevent environmental problems. Through the mixing of the recovered glass with calcium carbonate powder, glass foams can be synthesized that have applications in thermal and acoustic insulation. The various effects on the sintering process such as heating rate and holding time ...
The effective thermal conductivities of fully expanded intumescent chars are estimated using a finite element model related to porosity and density of the chars....
Through the use of the transient plane source method the researchers were able to measure the thermal conductivity of a collection of cellular metals as well as the in- homogeneities of the samples. The volume of the samples was varied and the density of these individual volumes was calculated from tomography....
The authors look into problems with accurately measuring thermal conductivity of liquid samples. Among these problems is the onset of natural convection during the measurement of thermal properties, which may lead to skewed values reported after characterization. The effect of natural convection is analyzed numerically for the transient plane source method in order to determine at what time during an analysis the convection causes incorrect output data. The effect of ...
Yttria-stabilized zirconia (YSZ) was synthesized by the spark plasma sintering process to generate pore-free, homogenous bulk samples that were then tested for thermal conductivity, which was measured by two separate methods: TPS and LFT. The TPS method was found to be better for measuring of thermal conductivity in this specific case. Using the phonon-hopping model (PHM) the authors were able to determine how grain boundaries of the bulk samples affected ...
