| چکیده | ||
| غربال استوانه‌ای دوار در مقایسه با سایر سیستم‌های تمیز کننده استفاده شده در کمباین‌ها، دارای ویژگی‌هایی همچون ساختار ساده‌تر، وزن سبک‌تر، لرزش و مصرف انرژی کم‌تر است. این نوع غربال همراه با جریان هوا می‌تواند به عنوان سیستم تمیز کننده جایگزین برای مخلوط برنج کوبیده شده، استفاده شود. در این پژوهش، برای تحلیل بهتر پارامترهای کاری غربال استوانه‌ای بر عملکرد جداسازی دانه از کاه، از کوپل دینامیک سیالات محاسباتیCFD) ) و روش المان گسستهDEM) ) استفاده شد. تاثیر سرعت جریان هوا و سرعت دورانی غربال بر شاخص‌های جداسازی شامل نسبت تمیزی، نسبت تلفات و بازده جداسازی بررسی شد. نتایج نشان داد که سرعت جریان هوا تاثیر قابل توجهی بر سرعت متوسط محوری اجزای مخلوط دارد. سرعت چرخش غربال تاثیر معنی‌داری بر نسبت تلفات و بازده جداسازی دارد. در این مطالعه به منظور شبیه سازی جریان گسسته مواد دانه‌ای، از نرم افزار Rocky DEM به عنوان جایگزین نرم افزار EDEM استفاده شد. نتایج پژوهش حاضر به کمک مطالعات گذشته که از نرم افزار EDEM برای شبیه‌سازی بهره برده بودند، صحت‌سنجی و تایید گردید. نرم افزار Rocky DEM توسط شرکت توسعه دهنده ANSYS Fluent ارائه شده، از این رو در شبیه‌سازی تعامل ذرات گسسته و جریان سیال به روش کوپل CFD-DEM می‌تواند جایگزین نرم افزارهایی مانند EDEM که پیش‌تر به طور گسترده در حوزه کشاورزی استفاده شده، گردد. | ||

| چکیده [English] | ||
| A cylindrical sieve, characterized by its simple structure, lightweight, negligible vibration, and lower energy consumption compared to other separation systems used in combines. This type of screen can serve as an alternative cleaning system for rice-threshed mixture when combined with air flow. This research employed computational fluid dynamics (CFD) and the discrete element method (DEM) to explore and enhance the understanding of the operational parameters influencing the performance of the cleaning sieve. The study examined the impact of air flow velocity and the rotational speed of the sieve on various separation indices, such as the cleanliness ratio, loss ratio, and efficiency. Findings indicated that air flow velocity significantly influences the average axial speed of the mixture components. The rotational speed of the sieve has a significant effect on both the loss ratio and the sieve's efficiency. In this study, Rocky DEM software was utilized as an alternative to EDEM for simulating the discrete flow of granular materials. The results of this study were validated through comparisons with earlier research that utilized EDEM software for simulations. Rocky DEM software developed by the provider of ANSYS Fluent, Rocky DEM enables the simulation of interactions between discrete particles and fluid flow using the coupled CFD-DEM method. Consequently, it serves as a viable replacement for EDEM, which has been extensively applied in agricultural research and engineering. | ||
