Multiphysics modeling of thermal processes in the end zone of a powerful generator
In the collective scientific monograph, researchers consider the issue of a comprehensive approach to carrier selection, analyze and study methods for determining flight options, choosing a stationary rfid reader, and a methodological approach to anti-aircraft missile system accounting; improve methods of parameterization of fuzzy cognitive models; analyze the logistical support of troops based on the experience of combat operations in Afghanistan.
The chapter, prepared by D. I. Khvalin, an employee of the ISP NPP of the National Academy of Sciences of Ukraine, shows the advantages of building mathematical models in the COMSOL Multiphysics software environment. The most significant advantage is the ability to solve multiphysics problems, which allows creating complex (interrelated) models. The algorithm, mathematical description and solution of the problem of determining the distribution of the electromagnetic field and temperature in the end zone of the stator core of a powerful turbogenerator in the case of using a numerical method are presented. An approach was used for the analysis of thermal processes in the end zone of the stator core of the turbogenerator of a sequential logical transition from a simple model of the electromagnetic field in the active part of the machine to more complex models of the end zone using the previous results in the following ones, which allows obtaining a solution for determining the temperature distribution in complex areas. The mathematical model differs from those used and known today by a more complete consideration of physical and technical factors and the reliability of calculation results under the conditions of simplicity of software implementation.
