چکیده

در مطالعه حاضر، میزان آنتروپی تولید شده ناشی از انتقال حرارت دوگانه نانوسیال ترکیبی درون محفظه K شکل تحت اثر میدان مغناطیسی یکنواخت و غیریکنواخت و جذب/تولید گرما یکنواخت بررسی شده است. شبیه‌سازی با نوشتن کد رایانه‌ای به زبان فرترن و با استفاده از روش شبکه بولتزمن صورت پذیرفته است. تغییرات عدد رایلی، عدد هارتمن، ضریب جذب/تولید گرما، نسبت هدایت حرارتی، نسبت ابعاد محفظه و نوع اعمال میدان مغناطیسی و کسر حجمی نانوذرات به عنوان متغیرهای اصلی این بررسی مورد ارزیابی قرار گرفته‌اند. نتایج نشان داد می‌توان قدرت جریان، میزان انتقال حرارت و آنتروپی تولید شده را با اعمال میدان مغناطیسی کاهش داد. کاهش کمتر عدد ناسلت متوسط با غیر یکنواخت اعمال کردن میدان مغناطیسی حاصل می‌شود. افزایش ضریب جذب/تولید گرما به دلیل افزایش دمای مجموعه منجر به کاهش عدد ناسلت متوسط می‌شود که این اثر با افزایش عدد هارتمن، بیشتر می‌شود. افزودن نانوذرات به سیال پایه در حالتی که هدایت پدیده غالب است، موجب افزاش میزان انتقال حرارت می‌شود. انتقال حرارت تابعی از نسبت ضریب هدایت حرارتی و عدد رایلی بوده و افزایش این دو پارامتر اثرات جابجایی را افزایش می‌دهد و در این شرایط، اثر افزایش عدد هارتمن نمایان‌تر است. افزایش نسبت ابعاد محفظه منجر به کاهش عدد ناسلت متوسط و آنتروپی شده ولی اثر افزودن نانوذرات در این حالت بیشتر است. آنتروپی تولیدی با افزایش عدد هارتمن کاهش و با افزایش عدد رایلی و ضریب جذب/تولید گرما افزایش می‌یابد.
