Abstract :
میکرومیکسرها بخش مهمی از سیستم‌های میکروسیالات هستند. در کار حاضر، اختلاط در سه سطح مقطع بررسی شده است. در اثر تولید گردابه های دین، شاخص اختلاط ۹۹ درصد در طول کوتاهتری از میکرومیکسر ودر رینولدز ۱۰ بدست آمده است. همچنین در مقایسه با سطح مقطع های مثلثی و دایره ای سطح مقطع مستطیلی راندمان بهتری دارد.
