| استفاده از امواج فراصوتی برای تهیه نانوامولسیون‌ها از مهم‌ترین موضوع‌های پژوهشی مرتبط با صنایع داروسازی، غذایی، مهندسی مکانیک و شیمی است. تاکنون در این روش از محفظه با مقیاس‌های مختلفی استفاده شده که با توجه به کاربرد و دقت مورد نیاز، انتخاب می‌شود. تعداد و نحوه قرارگرفتن سرامیک‌های پیزوالکتریک )پیزوها(، بسامد تحریک آ نها و میزان انحنا در لبه‌های محفظه، متغیرهای مختلفی در بهینه‌سازی طراحی یک حمام فراصوتی بوده که می‌توانند موجب تشدید یا خنثی شدن امواج با یکدیگر شوند. در این مقاله، طی 36 حالت، با استفاده از نرم‌افزار کامسول، به بررسی تأثیر شعاع لبه در چهار چیدمان مختلف از پیزوهای یک ریزمحفظ ه فراصوتی مکعبی پرداخته شده است. شعاع لبه در سه مقدار صفر، 5/ 2 و 5 میلی‌متر و تحریک پیزوها در بسامدهای 20 ، 200 و 300 کیلوهرتز ارزیابی شده‌اند. نتایج نشان دادند حذف لبه‌ها، تأثیر مثبتی بر انتشار امواج و افزایش چگالی انرژی آکوستیکی داشته و در بسامدهای کمتر و در چیدمان‌های دارای تعداد پیزوی بیشتر، محسوس‌تر است. صحت‌سنجی‌های تجربی نیز با تهیه نانوامولسیون در دو حالت حمام فراصوتی بدون شعاع لبه و با شعاع لبه انجام شد. نتایج آن، ضمن تأیید نتایج شبیه‌سازی، نشان داد که استفاده از حمام فراصوتی دارای شعاع لبه، موجب افزایش میزان پایداری فاز روغن در آب می‌شود. | ||

| Utilizing ultrasonic waves for nanoemulsion preparation is one of the most important research topics related to the pharmaceutical, food, mechanical and chemical engineering industries. The number and arrangement of the piezoelectric ceramics, the frequency of their excitation and the fillet radius of container’s internal edges are effective parameters in the design and optimization of an ultrasonic bath which cause either resonance or cancelation of the waves. In this paper, using COMSOL Multiphysics software, the simulations of the edge fillet radius effect in four different piezoelectric ceramics layouts of an ultrasonic microcontainer were performed in 36 possible configurations. In this way, the edge fillet radii and excitation frequencies of piezoelectric ceramics are simulated in zero,2.5 and 5 mm, and 20, 200 and 300 kHz respectively. It has been shown that although sharp edges elimination leads to improve acoustic energy density at all frequencies, however, arrangements which have more piezoelectric ceramics or lower frequencies are affected more. Experimental works were performed to prepare nanoemulsions in two modes of ultrasonic bath: with and without filleted edges. While approving the simulation outputs, the experimental results showed that the use of ultrasonic bath with filleted edges increased the stability of the nanoemulsion. | ||
