This paper introduces a compensation algorithm and a different-layers calibration method that will improve the temperature measurement speed and thermal resistance elimination of a guarded heat flow meter instrument. Without these additions to the method, heat will travel through a thin slice of material too fast for thermal couples to measure accurately. Thermal contact resistance would cause inaccuracy with a thin slice ...
The researchers propose an improvement in the theory of the transient plane source (TPS) technique. They claim that Gustafsson has ignored the contribution of the electrical resistance charge of the nickel double spiral and the heat capacity of the polyimide film surrounding the nickel spiral. The researchers developed improved mathematical equations to supposedly improve the accuracy of the technique by 1.8 to 2.3%....
