Abstract
The Thermo physical behaviour of soil is the fundamental behaviour and plays significant position in its “utilization” as “electrical and heat insulation”. However, numerous “researchers have studied” thermo-physical properties of soil. Still, the study on the relationship between soil's properties and its cooling effect through evaporation has not been investigated in detail. In this analysis, soil samples and earthen pots were collected from four states of India: Haryana, Delhi, Rajasthan, and Uttar Pradesh. The performance parameters used to evaluate the cooling effect of the soil, and earthen pot samples are “water-holding capacity”, porosity, “thermal-conductivity”, texture, and particle and bulk density. The application of “high temperature” fluctuate the “internal microstructure” of clay/soil and subsequently disturbs its “physical and thermal properties”. The sand/clay is converted into an earthen pot by applying high temperatures in kilns. The pot samples collected are heated in kilns to bring them to the final form for the study. We are studying the properties after that treatment. In this paper, the impact of “firing temperature” (maximum 900°C) on the “thermo-physical properties” of earthen pots made up of soil of a similar kind as the soil samples collected and the impact of thermo-physical properties on the cooling of the earthen pots has been examined via experiments. The results specify that the “thermal conductivity” of soil/clay samples is less compared to earthen pot. The “porosity and water-holding capacity” of the soil are greater than earthen pots because pore space or pore volume has decreased due to the heating effect. From the experimental analysis, it was found that the soil of the Sohna location in Haryana state has a high water cooling capacity due to its high water-holding (49.28%) capacity and porosity (48.75%). The pot made out of clay, having higher porosity, and water-holding capacity, gives the maximum cooling temperature.
