|Title:||Transient Method For Measuring Thermal Properties Of Saturated Porous Media|
|Abstract:||This paper describes the development of a transient technique to measure thermal diffusivily and conductivity of porous samples. The method uses the film heat sensor to probe heat flux. Temperature and heat flux are 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 finally tested in the laboratory, with experiments made on samples of natural rock. © 1993 Pergamon Press Ltd.|
