The objective of this study was to evaluate the transient plane source method for thermal conductivity and diffusivity of food and agricultural materials. An instrument was used to measure thermal conductivity of liquid and solid samples. Thermal conductivity and diffusivity values determined by the TPS method were in close agreement with reported literature values....
Since there was no literature on using the transient plane source method for the measurement of thermal conductivity and diffusivity of food products the authors did it themselves. They tested a variety of products including water, mineral oil, ethanol, beef, chicken and apples and determined that using the transient plane source method to simultaneously measure thermal conductivity and diffusivity was an accurate method....
