Аннотация
В работе приведена математическая модель и вычислительный алгоритм для исследования задачи процесса фильтрования ионообменной сорбции двухкомпонентных растворов. Модель представлена в виде систем нелинейных дифференциальных уравнений в частных производных второго порядка. Нелинейные члены математической модели линеаризованы по методу Бельман-Калава. Математическая модель решена численно с использованием метода векторной конечно-разностной схемы Самарского-Фрязинова. Разработано программное средство для определения изменения концентрации первого и второго компонента суспензий. С помощью, разработанного программного средства проведены численные эксперименты на ЭВМ при задании различных режимов работы фильтрующего агрегата, приведены результаты и их интерпретация в табличном виде, а также выводы по проведенному исследованию в целом.
The paper presents a mathematical model and a computational algorithm for studying the problem of filtering ionexchange sorption of two-component solutions. The model is represented in the form of systems of nonlinear partial differential equations of the second order. The nonlinear terms of the mathematical model are linearized by the BelmanKalava method. The mathematical model was solved numerically using the finite-difference vector scheme of Samaraskiy-Fryazinov. In the numerical solution of the problem, a software has been developed to determine the change in the concentration of the first and second components of the suspensions. The results of the numerical computer experiments were carried out with the setting of different operation modes of the separating unit, as well as their interpretation in tabular form and conclusions on the study as a whole.
Ishda ikki tarkibli aralashmalarni filtrlash jarayonining ionalmashinuv sorbsiyasi masalasini tadqiq etish uchun matematik model va hisoblash algoritmlari keltirilgan. Matematik model ikkinchi tartibli hususiy hosilali differensial tenglamalar sistemasi ko’rinishda ifodalangan. Matematik modelning chiziqsiz hadlari Belman – Kalava usuli yordamida chiziqli ko’rinishiga keltirildi. Matematik model Samarskiy-Fryazinovaning vektorli chekli ayirmali usulini qo’llash orqali yechildi. Suspenziyadagi birinchi va ikkinchi tarkibli aralashmaning konsentrasiyasini hisoblash dasturiy vositasi yaratildi. Yaratilgan dasturiy vosita asosida tozalovchi agregatlarning turli ish rejimi qiymatlari uchun EHMda o’tkazilgan hisoblash tajriba natijalari va ularning qiymatlari jadval ko’rinishida keltirilgan hamda butun izlanishlarning umumiy hulosalari chiqarilgan.
