A new analysis method based on the guarded heat flow meter apparatus is proposed to measure the thermal properties of cement-based pastes in a hydrated form. In a steady state, a specimen with 0.4 water-to-cement ratio was found to have a thermal conductivity and a thermal contact resistance of 1.28Wm−1 K−1 and 0.038 m−2 KW−1. A computerized system of heat flow meters provided non-steady ...
The variability within the results presented from the guarded hot-plate (GHP) and guarded heat-flow meter (GHF) methods was determined. Multiple thermal properties of polymethyl methacrylate (PMMA) were analyzed to compare methods. These measurements are taken in the range of −70◦C and +80◦C. Providing reference data for PMMA is the main objective of this paper as well as quantifying the effects of thermal contact of the measuring instruments....
Extreme care must be taken regarding the proper processing and storage of market seafood the correct amount of heat transfer with occur in order to deliver healthy and fresh tasting food. Measurements of the thermal conductivities of big-eyed tuna and pacific cod were taken with a modified transient line source probe method in a temperature range of 5 - 50°C. Accurate predictions are ...
This paper explore the measure taken to promote extreme care of the processing of both fresh and dry fish to achieve the desired heat transfer. The paper deals with finding the thermal conductivity and thermal diffusivity of several species of fresh and dry fish by using the transient line source technique. These conductivity values ...
High temperatures play a crucial role in the deterioration of the thermal properties of rocks and can threaten the structural integrity of many applications in engineering. This research focused on the variations in thermal diffusivity of sandstone after high temperature heating. Thermal properties of the samples were measured before and after heating using a thermal constants analyzer based on the Transient Plane Source (TPS) technique. Thermal diffusivity of the sandstone ...
