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

压实和温度对复合粘土材料热性能的影响

这项工作的目的是根据不同温度(20°C、30°C、40°C和50°C)的压实率，确定红土块的热性质(导热系数、体积热容、热扩散率和热渗出率)的变化。用不同的离心重量(250g、500g和1000g)压实若干红土样品。利用ct仪，实验测量了这些样品在不同温度下干燥状态下的热性能。实验结果表明，随着压实率的增加，这些热性能显著增加。然而，随着温度的升高，所研究样品的热性能下降。收稿日期:2023年7月5日修稿日期:2023年8月15日收稿日期:2023年8月25日

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.
