چکیده

در این پژوهش، انتقال حرارت جابجایی اجباری جریان آرام نانوسیال آب - مس درون کانال با صفحات موازی با منابع حرارتی دما ثابت، به صورت عددی بررسی شده است. هدف، بررسی عددی تأثیر عدد رینولدز، درصد حجمی نانوذرات و تعداد منابع حرارتی روی میدان جریان و نرخ انتقال حرارت می‌باشد. معادلات حاکم به روش حجم کنترل جبری شده و توسط الگوریتم سیمپل به طور هم‌زمان حل شدند. نتایج نشان می‌دهند که افزایش درصد حجمی نانوذرات و افزایش عدد رینولدز، هم‌چنین تقسیم یک منبع حرارتی به قسمت‌های کوچکتر و توزیع آنها، نرخ انتقال حرارت را افزایش می‌دهند.
