Assorted potential thermal insulators are fabricated nowadays for possible applications in various fields. Unfortunately, drawbacks like selective suitability, unavailability, and expensiveness hinder the progress in the usage of several devices that are efficient and suitable for probing the thermal conductivity values of such materials. Though the observed challenges can be overcome by using the traditional Lee–Charlton's Disc (TLD) apparatus, a long-time duration is usually required for the set-up to attain steady state. In this work, a modified Lee–Charlton's Disc (MLD) apparatus set-up has been designed and put to use. The results showed decrements by 65.66% to 71.87% in the steady-state duration when using the MLD apparatus. By employing the MLD apparatus, thermal conductivity values were determined for thermal insulators with thickness of up to about 9.0 mm. The repeatability and reproducibility of the MLD apparatus satisfied the conditions for unconditional acceptability of a test device/method. [ABSTRACT FROM AUTHOR] |
