Condensed Materials Thermal Diffusivity Measurements Using Temperature Waves Method in Adiabatic Regime

Abstract:

Temperature wave method is a quasi-stationary method for measuring thermal diffusivity of a substance. Method of plane temperature waves is a derivative of temperature wave method based on the notion of applying heat flux to first side of a sample and measuring temperature fluctuation on the second side of a sample. Changing temperature wave frequent allows us to enter adiabatic regime. Considering that phase of heat flux is known, the only parameter to be measured is phase of temperature changes on the second side of a sample relative to the phase of heat flux, which (in adiabatic regime) gives us thermal diffusivity.
