Abstract
The process of transferring thermal energy (heat) distributed in nature are largely determined by the practical activities of man. The concept covers the entire range of heat transfer phenomena of heat in space caused by temperature difference Geotechnical individual elements of the system. In general, the heat transfer is a complex process associated with a variety of physical phenomena, but there are three main types (mechanism) heat, thermal conductivity, convective heat transfer and heat radiation. Since these phenomena occur and geotechnical conditions of any level, then they are considered in detail. Heat of geotechnical system is a combination of many different origins thermal fields: natural - geothermal gradient, heat tectonic, magmatic, volcanic and seismic processes, energy and hydrothermal fluid flow, etc. Others - man-made, such as thermal pollution from industrial and mining enterprises, various waste heat process water, underground recycling, gasification and combustion of fuel and others. Given the composition of Geotechnical multiphase system, we have to divide the heat transfer mechanisms in each of its components. The variety of thermal processes instituted mountain range requires additional analysis, parameterization and develop a holistic approach to predicting system behavior and calculation parameters for the purpose of managing its elements in difficult conditions geotechnical systems.
Highlights
The thermal energy of a geotechnical system is a composition of many thermal fields of different origin
In a general case the coefficient of heat transfer is affected by geometrical sizes and shape of a body, the temperature of its surface, the nature of development and regime of fluid movement, velocity, temperature, physical parameters of fluid and many other factors
Because heat transfer in fluids is considered as a continuous medium, the theoretical study of convective heat exchange leads to defining of the relations for the field of velocity, pressure, temperature and physical capacities
