測定の適用性拡張の試み

抄録

The object of this study is to research the possibility of in-line measurement of the thermal diffusivity on composite materials by previously developed apparatus for the dynamic viscosity. The basic method to obtain thermal diffusivity has been proposed in the 1st report. In this study, the influence of the factors, such as the heating rate from heater and the distance between heater and temperature measurement probe, are studied to apply more wider range on composite materials. The new data having within ±10% accuracy are obtained about various food materials. The arrangement expressions are tried on calibration curve, and we propose Eqs. (2) and (3) as 1st approximation.
