The article provides an experimental analysis of the behavior and changes in thermophysical properties of the thermal insulation systems most commonly used in construction during the entire life of the buildings. Experimental data on temperature fluctuations and distribution of heat flow density of a thermally modernized section of a wall-enclosing structure insulated by various methods for 6 years...
Open cavity solar receivers play an important role in concentrated solar power (CSP) systems and hold great promise, particularly in scenarios where their ability to absorb high fluxes at very high temperatures yields beneficial results. This intense concentration of sunlight can be used to produce electricity through various means, such as generating steam to drive a turbine. The efficiency of the...
This paper analyzes the results of studying contaminated soil samples from a combat zone (Sumy region, Ukraine). The authors proposed a mathematical model for simulating and assessing the impact of military operations on soil and groundwater. The mathematical model will make it possible to predict the occurrence of environmental emergencies and reduce the frequency of expensive experimental studies...
The article presents studies of the drying kinetics of composite raw materials based on solid peat residues after extraction of the humus component and corn harvesting residues. The resulting heat of combustion of composite raw materials is 1.2-1.4 times higher than that of peat in its native state. Moreover, their fairly high calorific value allows them to be used as an alternative fuel in domestic...
