DEVELOPMENT OF A SINGLE-SIDED GUARDED HOT PLATE APPARATUS FOR THERMAL CONDUCTIVITY MEASUREMENTS

ABSTRACT
This work presents the development of an experimental setup for measurements on of thermal conductivity of solid materials, such as ceramics, polymers, rubbers, glasses, biological materials, etc. whose thermal conductivity lies in the approximate range between 0.1 and 2 Wm-1K-1. The setup was designed on the principle of the single-sided guarded hot plate method. In order to find the optimal design for generation of traceable one-dimensional heat flux through an investigated 300×300 mm2 specimen, a numerical heat transfer FEM analysis was performed. The principal components of the measuring apparatus, such as hot plate with thermopile, cold plate and auxiliary hot plate were constructed according to the obtained results of simulations. Software for the control of experiment and data acquisition was developed using the LabVIEW programming environment.
