Some operations of technologies for the production of porous composite materials, the thin film formation on the surface of products are considered in the absence of gravity. Mathematical models of melting polymer coating of a set of hollow microspheres due to the heat of the superheated melt between them, the flow of a thin layer of liquid along the surface of the cylinder are given. The solution of the corresponding problems is carried out analytically and numerically using the software package OpenFOAM. Estimates of the dynamics of the interphase boundary, the time of operation, the thickness of the coating were obtained.
In conclusion, recommendations are given, the implementation of which will improve the quality of the resulting materials, formed coatings.

Математическое моделирование процессов, протекающих при получении пористых композитных материалов, формировании покрытий

В отсутствие сил тяжести рассмотрены отдельные операции технологий получения пористых композитных материалов, формирования на поверхности изделий тонких пленок. Приведено математическое описание расплавления полимерного покрытия совокупности полых микросфер за счет тепла находящегося между ними перегретого расплава, течения тонкого слоя жидкости по поверхности цилиндра. Решение соответствующих задач осуществляется аналитически и численно с использованием пакета прикладных программ OpenFOAM. Представлены оценки динамики межфазной границы, времени выполнения операции, толщины покрытия.
В заключение даны рекомендации, реализация которых позволит повысить качество получаемых материалов, наносимых покрытий.
