The difficult environmental situation in the world is largely a consequence of the huge volume of production and consumption waste and its constant growth. In this regard, the problem of waste placement, neutralization and utilization comes to the fore. One of the most controversial methods that contribute to a significant reduction in the amount of garbage and the production of energy is waste incineration plants. The main argument of opponents of this method of disposal is the assertion about the pollution of th...

The regular mode of the 3rd kind (method of periodic heating) is one of the effective ways to measure a complex of thermal characteristics (thermal conductivity, thermal diffusivity and heat capacity) of gases and liquids (see, for example, the works of L.P. Filippov and S.N. Kravchun). Currently, this method has become widely used to study the thermal properties of solids. In our works, schemes of the process of heat transfer in the system of three contacting bodies ? the sample under study and two semi-limited (...

Currently, the population of the Earth, reaching a value of 7.2 billion people (2014), continues to grow rapidly. This leads to an increase in the demand for food, energy, minerals, which in turn enhances the anthropogenic impact on the biosphere, at the same time increases production and consumption waste and worsens the ecological situation. The problems of urbanization should be attributed to the most acute technospheric problems - increasing the role of cities in the development of society, as well as the grow...

The reliable determination of solid material thermal properties (thermal conductivity, thermal diffusivity and heat capacity) are significant for various industries. Knowledge of thermophysical characteristics of reservoir rocks is essential in developing high viscous oil deposits by thermal methods. One of the biggest problems in experimental investigation of thermophysical properties concerns with measurement errors due to multidimensional character of thermal flow (generally, in most cases, one-dimensional theo...

Periodic thermal processes and periodic temperature fields are well represented in nature and technology. In nature, they occur largely due to periodic processes such as one year Earth's orbital motion, day and night cycle of the Earth's rotation around its own axis, etc. With conductive heat transfer mechanism daily temperature fluctuations almost damp in a layer thickness of about 1 m, annual temperatures do it in layer of 18 to 21 m thick. In the case where periodic heating by the Sun coincides with the mass tr...
