Building materials processing with the help of HF waves demonstrates a great number of perspective advantages as compared to traditional heating methods. In order to upgrade the technology of HF wave heating there exist a need to optimize the HF waves sources that enable us to consider some characteristic features of the process to a greater extend. To solve the task of optimizing a HF wave energy source we use the methods of the optimal control theory. The optimization has been carried out based on the gradient method. As a result we have found some optimal functional dependencies that describe the laws strength change of an electrostatic and a high-frequency field. Established managements help considerably enhance the efficiency of the energy exchange. The calculations we have carried out show that the chosen method enables an efficient optimization of a HF wave energy source with different restrictions of the governing function.

Building materials microwave processing demonstrates a great number of perspective advantages as compared to traditional heating methods. In order to upgrade the technology of microwave heating there has been developed a mathematical model of the technological process of microwave energy heat treatment of loose building materials. As a result we have won some calculation correlations, developed a numerical model and calculation algorithms for the analysis and synthesis of the microwave dryer of a loose dielectric with losses while it moves along the working camera. The results of the practical calculations have been carried out with the regard for water load and without it, also with the regard for the changes of the electro- and thermal-physic parameters during the heat treatment as well as disregarding them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
