This article is devoted to the complex research method based on mathematical modeling and visualization of thermal fields, which allowed one to obtain the optimal parameters of heat transfer elements of the spacecraft systems of air heating of buildings.
RESOURCE-SAVING TECHNOLOGIES OF TREATMENT OF POLLUTED WASHING WATER FOR TRANSPORT COMPANIESSummary. Dedicated to the development of resource-saving polluted washing water treating technologies for transport companies. The article suggests methods of water purification with regard to scientifically grounded requirements to the quality of the water used and the required degree of purification and The article also considers the method of selecting efficient methods of sewage water treating, when a selective removal of individual polluting ingredients should be done. For this purpose we have conducted a simulation process of treating polluted washing water in the circulating water systems, and provided solutions for refining the process parameters.
РЕСУРСОСБЕРЕГАЮЩИЕ ТЕХНОЛОГИИ ОЧИСТКИ ЗАГРЯЗНЕННЫХ МОЕЧНЫХ ВОД НА ПРЕДПРИЯТИЯХ ТРАНСПОРТААннотация. Посвящено разработке ресурсосберегающих технологий очистки загрязненных моечных вод на предприятиях транспорта. В статье рассмотрены методы очистки воды с учетом научно-обоснованных требований к качеству используемой воды и необходимой степени очистки и методики подбора селективных рациональных методов очистки сточных вод, когда удаление отдельных ингредиентов общего загрязнения происходит избирательно. Проведено моделирование процесса очистки загрязненных моечных вод в оборотных системах водопользования и даны решения задач оптимизации параметров процесса.
Air heating systems of buildings are resource-consuming systems, for this reason, improving their resource efficiency appears to be of great significance. The author have developed a mathematical model of process of heat exchange in heat exchange surfaces of apparatuses with the solution of multicriteria optimization problem, an optimal range of managed parameters influencing the process of heat exchange with minimal metal consumption and the maximum heat output fin heat exchanger, the regularities of heat exchange process with getting generalizing dependencies distribution of temperature on the heat-release surface of the heat exchanger engineering systems of buildings, defined convergence of the results of research in the calculation on the basis of theoretical dependencies and solving mathematical model. Finding the best managed of the parameters of the heat exchanger element air heating system of a building is possible with the developed by the author of a comprehensive method of research based on multi-criteria parameters optimization with the introduction of empirically obtained data.
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.
