This paper reviews the effect on measured thermal conductivity using the transient line source focusing on the effect of weak radiative heat transfer. Relations between the parameters that determine the thermal conductivity and the radiative heat flux and temperature distributions are discussed. The optical condition resulting in the maximum radiation is found. ...
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 ...
