چکیده: (668 مشاهده)
در این پژوهش، به بررسی اثرات دامنه بیبعد و فرکانس جریان پالسی برروی نرخ انتقال حرارت از سیلندر دایروی در حضور و عدم حضور صفحه جداکننده پرداخته شده است، بدین منظور، ابتدا به بررسی نرخ انتقال حرارت جریان غیرپالسی پرداخته شده و سپس با نتایج بهدست آمده از جریان پالسی مقایسه شده است. جریان پالسی عبوری از یک سیلندر دایروی در محدوده عدد استروهال پالسی (2-1/0) و دامنه بیبعد جریان پالسی 75/0 A= در عدد رینولدز 100= Re مورد بررسی قرار گرفته است. جریان پالسی یکی از عواملی است که میتواند روی نرخ انتقال حرارت مؤثر واقع شود. اما به صورت کلی، تغییر در نرخ انتقال حرارت تحت جریان پالسی وابسته به دامنه بیبعد و فرکانس جریان پالسی میباشد. بهترین حالت جهت افزایش نرخ انتقال حرارت زمانی است که صفحه جداکننده به جسم چسبیده شده باشد. در تمام محدوده استروهال پالسی، افزایش در عدد ناسلت در حضور صفحه جداکننده نسبت به عدم حضور صفحه جداکننده تحت جریان پالسی گزارش شده است.
