On Experimental Thermal Analysis of Solid Materials

Abstract: The paper is devoted to the presentation of a method for measurement of thermal conductivity k, specific heat capacity c p , and thermal diffusivity applying the lumped capacitance model (LCM) as a special case of Newton's model of cooling. At the specific experimental conditions resulting from the theoretical analysis of the used model, we present a method for experimental determination of all three above mentioned thermal parameters for materials with different thermal transport properties. The input experim… Show more

“…The safety of maintenance staff and quality controllers, who will no longer have to physically inspect equipment located in hazardous locations, cannot be neglected. Research has also led to cooperation with an international metal company, which has promised partial co-financing for research into the device, so that there is a high probability that the device will be the new standard, launching a new era of measurement and analysis in heavy industry, particularly in areas described in [12][13][14][15].…”

“…This procedure together with the adiabatic chamber construction satisfies the validity of Lumped capacitance model. The tests of measured data show the relatively narrow interval of reliability equal approximately up to 5 percent [15].…”

“…Such law is not generally correct but it is a good approximation for temperatures not too high and not large temperature intervals. In fact, the energy transfer from an object to its surrounding is not only due to conduction and convection but also to radiation, and the latter does not vary linearly with temperature difference, which leads to deviations from Newton's law [1][2][3].…”
