چکیده

جداکنندههای چندفازی گرانشی یکیاز مهمترین تجهیزات برای جدایش فازهای با ارزش در صنایع مختلف بهشمار میروند. بهدلیل ضعفهای مربوطبه مدل‌های نیمهتجربی و هزینه‌های بالای انجام آزمایش برای یافتن طراحی بهینه برای این جداکنندهها، استفاده از دینامیک سیالات محاسباتی (CFD) رو به گسترش است. در اینتحقیق پس از مرور کلی جداکنندههای گرانشی به بررسی مروری بر کارهای انجامشده با استفاده از CFD برای انتخاب مدل مناسب در طراحی و بهینهسازی جداکننده‌ها،پرداخته شدهاست. نتایج نشا‌ن‌میدهد که اگرچه استفاده از CFD یکروش قدرتمند برای مدل‌سازی و بهبود طراحی جداکننده است ولی کاستی‌های آن همچون استفاده از مدل نادرست، فرضیات ساده‌کننده و روش بهینهسازی نامناسب، منجربه نبود دقت کافی در نتایج شبیهسازیو بهینه‌سازی شدهاست که باید در کارهای آینده بررسی شوند.

چکیده [English]

Gravity multiphase separators are one of the most important equipment in different industries. Due to the limitations related to semi-empirical models and the high-performance cost of experimental tests in finding the optimized design, computational fluid dynamics (CFD) has been widely used recently. In this research, after a total review on gravity separators, a review of CFD studies on these apparatuses, to find the appropriate model for simulation and optimization, are considered. Results show that, although CFD is a powerful technique for modeling and improving the separator design, some disadvantages like using incorrect models, simplified assumptions and inappropriate optimization methods lead to inaccurate simulation and optimization results, which should be considered in future works.
