Очистка газовых потоков является важной задачей многих отраслей промышленности в области инженерной защиты окружающей среды. При осуществления подобных мероприятий зачастую применяются циклоны – аппараты для очистки газовых потоков от мелкодисперсных частиц. В фармацевтической промышленности для решения таких задач требуется применение компактных высокоэффективных аппаратов, для разработки и исследования которых в последнее время все чаще применяются методы CFD-моделирования. В работе приводится сравнение результатов CFD-моделирования процесса очистки газа в прямоточном циклоне новой конструкции и эффективности улавливания в этом аппарате, полученной в результате экспериментальных исследований.</p></sec><sec><title>Цель</title><p>Цель. Сравнение результатов численного моделирования процесса очистки газа в двух конфигурациях прямоточного циклона новой конструкции с результатами эксперимента.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для численного CFD-моделирования процесса разделения в исследуемом аппарате использовался программный комплекс FlowVision. Движение дискретной фазы – частиц – описывалось с помощью Lagrangian particle model. Для распределения частиц по размерам использовалось распределение Розина – Раммлера с минимальным диаметром 15 мкм, медианным 40 мкм и максимальным 120 мкм. Эксперименты проводились на экспериментальной установке, основной частью которой являлись прямоточный циклон, центробежный вентилятор и шнековый дозатор. В качестве модельного материала использовался тальк марки ТРПН, дисперсное распределение частиц которого было определено методом лазерной дифракции на анализаторе частиц SALD-2300 (Shimadzu, Япония).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. CFD-модель аппарата позволила определить поле скоростей газа, траектории потока и эффективность улавливания частиц в исследуемых конфигурациях прямоточного циклона. На основании информации о поле скорости газа и траекторий потока сделаны выводы о наиболее эффективных конструкторских решениях. Сравнение результатов численного моделирования и результатов эксперимента показало хорошую сходимость.</p></sec><sec><title>Заключение</title><p>Заключение. Разработанная конструкция прямоточного циклона показала хорошую эффективность улавливания мелкодисперсных частиц. Численное CFD-моделирование позволило определить конструктивные особенности, негативно влияющие на эффективность, и оптимизировать конструкцию аппарата. Хорошая сходимость результатов модели и эксперимента подтверждает возможность использования CFD-программ для точного моделирования технологических процессов и определения их параметров.  </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Purification of gas streams plays an important role in many industries in the field of environmental engineering. When implementing such measures, cyclones are often used – devices for cleaning gas streams from fine particles. In the pharmaceutical industry solving such problems requires the use of compact, highly efficient devices, for the development and study of which CFD-modelling methods have recently been increasingly used. The paper presents a comparison of the results of CFD-modelling of the gas purification process in a direct-flow cyclone of a new design and the capture efficiency in this apparatus obtained as a result of experimental studies.</p></sec><sec><title>Aim</title><p>Aim. Comparison of the results of numerical modelling of the gas purification process in two configurations of a direct-flow cyclone of a new design with the experimental results.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The FlowVision software package was used for numerical CFD-modelling of the separation process in the studied device. The motion of the discrete phase – particles – was described using the Lagrangian particle model. Rosin-Rummler distribution with a minimum diameter of 15 microns, a median of 40 microns, and a maximum of 120 microns was used to distribute the particles by size. The experiments were carried out on an experimental setup, the main part of which was a direct-flow cyclone, a centrifugal fan and a screw doser. Technical talc was used as a model material, the dispersed particle distribution of which was determined by laser diffraction on a SALD-2300 particle analyzer (Shimadzu, Japan).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The CFD-model of the device allowed us to determine the gas velocity field, flow trajectories and particle capture efficiency in the studied configurations of a direct-flow cyclone. Based on the information about the gas velocity field and flow trajectories, conclusions were made about the most effective 4 design solutions. Comparison of the numerical simulation results and the experimental results showed good convergence.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed design of the direct-flow cyclone showed good efficiency of fine particle capture. Numerical CFD-modelling allowed us to determine design features that negatively affect the efficiency and to optimize the design of the device. Good convergence of the model and experimental results confirms the possibility of using CFD-programmes for accurate modelling of technological processes and determining their parameters.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>прямоточный циклон</kwd><kwd>пылеулавливание</kwd><kwd>CFD</kwd><kwd>FlowVision</kwd><kwd>закрученный поток</kwd><kwd>численное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>direct-flow cyclone</kwd><kwd>dust collection</kwd><kwd>CFD</kwd><kwd>FlowVision</kwd><kwd>swirling flow</kwd><kwd>numerical modeling</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (проект 21-79-30029).</funding-statement><funding-statement xml:lang="en">The study was supported by a grant from the Russian Science Foundation (project 21-79-30029).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Yu G., Dong S., Yang L., Yan D., Dong K., Wei Y., Wang B.
