APPROXIMATE-ANALYTICAL SOLUTION FOR HEAT REMOVAL FROM A SPHERICAL BODY IN THE GROUND

Regulation of the thermal regime of the soil in greenhouses assumes particular urgency in light of the need to
remove excess low-potential heat from thermal power plants. In this paper, a method for analytical calculation
of heat removal from a sphere immersed in the ground of a greenhouse is developed. Based on the calculation,
dependences of the specific heat flux are constructed on changes in the following parameters: ambient and soil
surface temperatures, depth of occurrence and diameter of the spherical body, coefficient of heat emission from
the ground surface to air, and thermal conductivity of the soil. This mathematical model can be used to predict the
temperature regime of the soil during subsoil heating
