This study aimed to determine how reliable the Transient Plane Source (TPS) method is when testing semi-transparent materials that have varying extinction coefficients at different temperatures. A numerical experiment has been designed that copies the experimental process and tests the accuracy of the thermal conductivity values that the TPS method generates for semi-transparent materials. After using the TPS Method and comparing the results with the numerical experiment, the study concluded ...
The effective thermal conductivity of a commercial silica aerogel is determined at various gas pressures ranging from 0.001 Pa to 1 MPa in order to determine the contribution of gaseous heat conduction to the effective thermal conductivity of nano-porous materials. It was determined that the gas pressure had a significant effect on the effective thermal conductivity of the aerogel and that the contribution of gaseous heat conduction was greater than the gas ...
