Poljakov of National Academy of Sciences of Ukraine popup.description2  As a result of researches on the topic the numerical method has been developed and a discrete analogue of the mathematical model equations has been constructed for calculating gas-dynamic and heat exchange processes under the influence of high-temperature plasma heat carrier on natural and man-made materials in thermal rock destruction technology, which moves in the channel with heat exchange processes in the surrounding solid material. The scheme of the stand for researches process transformations of the heterogeneous carbon-containing environment in gas of the increased caloric content is developed and the basic indicators of physical modeling steam-plasma process reception synthesis gas of the increased caloric content are established. A universal mathematical model of vibro-shock systems used in technologies for processing natural and technogenic materials and a computational algorithm of the model have been developed. Studies of vibro-shock systems have been performed, the results of which indicate the adequacy of the reflection of the mathematical model of dynamic processes in vibro-shock systems. Due to the generalization of the mathematical model of thermal and hydraulic processes in porous freon steam generators for boundary conditions of the first kind, thermodynamic characteristics for a cylindrical porous channel are obtained. Using the Redlich-Kwong equation to model the thermal properties of CFCs, the mathematical model of CFC expansion in stationary turbine nozzles was improved, and the mathematical model of thermophysical processes of a CFC steam generator was improved, taking into account the power of the low-potential heat source to be used.
