DEVELOPMENT OF A METHOD OF SIMULTANEOUS DETERMINATION OF THE CONDUCTIVITY AND THERMAL DIFFUSIVITY OF MATERIALS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 1
Abstract
There are several methods of measures of thermo physical properties. The methods of transient state are used to determine the thermal diffusivity and those of steady state who used to determine the thermal conductivity. Most of the devices sold commercially allow measuring these properties on separate tests. In this paper we have developed a method that allows measuring simultaneously the thermal diffusivity and the thermal conductivity in a single operation. For that we build a very simple device. This new methods is obtained by solving the transient heat diffusion equation with the method of Duhamel leading to expressions of diffusivity and conductivity for understanding how to perform measurements in transient and permanent to measure these parameters. The validation of the theoretical model was made from two reference materials: plaster and extruded polystyrene.
