Transient method for measuring thermal properties of saturated porous media.

Type of article: Article

Summary

The paper describes the development of a transient technique to measure thermal diffusivity and conductivity of porous samples. The method uses the film heat sensor to probe heat flux. Temperature and heat flux were measured dynamically, allowing conditions to vary in time at the point of measurement. The data are then treated by a deconvolution algorithm, rendering results proper to simpler models for the same geometry. The numerical treatment in the deconvolution procedure was verified for a hypothetical case. The method was tested in the laboratory, with experiments made on samples of natural rock.
