Lushpenko S. Simulation of heat processes in ceramic and superhard materials with identification of their thermal properties

The subject of the study is steady and transient thermal processes in the solid body, their influence on the operating characteristics of the thermally loaded articles, and also the thermophysical characteristics of the materials, of which these articles are made. The purpose is studding the thermophysical characteristics of new materials and laws governing the flow of thermal processes in the elements of thermally loaded equipment, made of these materials. Methods of study are methods of theory of thermal conductivity and technical thermal physics. Theoretical and practical results consist of automated fitting method; the improved algorithm for solution of the nonlinear direct heat conduction problem; the thermophysical properties of ceramic materials, amorphous metallic alloys and superhard polycrystalline materials; the data about a change of the temperature field of a cooled ceramic board depending on the intensity of cooling, and the temperature fields in the cutting elements, which is sharpened with grinding; the data base about the thermophysical properties of solid, liquid and gaseous substances. Novelty: as a result of conducted investigations the urgent scientific problem of the complex determination of thermophysical properties and temperature fields in the objects made of new and barely studied materials is solved. The realization level: developed methods and software are used in the research, practical and training practice, which is confirmed by five acts of introduction and use. Field of use is engineering thermal physics.
