Abstract
The object of this study is to research the possibility of in-line measurement of the thermal diffusivity on composite materials, such as suspension and emulsion, by previously developed apparatus for the dynamic viscosity.
The calibration curve between the thermal diffusivity and any physical quantity that can be measured by this apparatus is proposed by the numerical analysis. The experimental results were obtained by using the dispersed materials composed agargel cooking oil (as matrix) and Ti02 particle.
Nondimensional effective thermal diffusivity that is the ratio of the effective thermal diffusivity of dispersed materials to the one of the matrix are compared with previous results obtained by periodic heating method. These data of nondimensional values show good agreement with each other. From these results, this measurement apparatus may be applicable for the thermal diffusivity measurement of dispersed materals.
