Abstract
The objective of this work is to determine the variation of thermal properties (thermal conductivity, volumetric heat capacity, thermal diffusivity and thermal effusivity) of red earth blocks, according to the compaction rates at different degrees of temperatures (20°C, 30°C, 40°C and 50°C). Several red earth samples were compacted with different centrifugal weights (250g, 500g and 1000g). Using the CT-meter, we measure the thermal properties of these samples experimentally in the dry state at different temperatures. The experimental results obtained show a significant increase in these thermal properties with the increase in compaction rate. However, as temperature increases, the thermal properties decrease for the samples studied. Received: July 5, 2023Revised: August 15, 2023Accepted: August 25, 2023
期刊介绍：
The JP Journal of Heat and Mass Transfer publishes peer-reviewed articles in heat and mass transfer which enriches basic ideas in this field and provides applicable tools to its users. Articles both theoretical and experimental in nature covering different aspects in the area of heat and mass transfer such as heat transfer in phase change phenomena, machinery and welding operations, porous media and turbulence are considered. Priority is given to those which employ or generate fundamental techniques useful to promote applications in different disciplines of engineering, electronics, communication systems, environmental sciences and climatology. Because a combination of two or more different technologies in a single device may result into a significant development, the journal extends its scope to include papers with the utility value in electronics and communication system. In this spirit, we are devoting certain number of issues to ‘Mechanical Systems and ICT – Convergence’. Survey articles dealing with certain issues in the context of current developments in heat and mass transfer together with their applications in interdisciplinary topics are also entertained.
