چکیده
In this study, a novel design was proposed for enhancing heat transfer in a channel with metal foam, corrugated walls, and hybrid nanofluids. The numerical analysis of hybrid nanofluids (MWCNTs+TiO2) with DW (distillate water) as the base fluid was performed in a channel with triangular corrugations and open metal foam. The mass fractions of hybrid nanofluids (mixture of DW and MWCNTs+TiO2) were set at 0.025%, 0.05%, and 0.075%. The effects of metal foam porosity and PPI (pore density), as well as different Reynolds numbers (ranging from 7000 to 13000), on thermal performance were investigated. The results showed that the heat transfer enhancement with metal foam increased by 130% for all hybrid nanofluids. Moreover, the heat transfer enhancement in metal foam with a porosity of 0.9 was 9.8% higher than that of metal foam with a porosity of 0.99. Additionally, quadratic correlations for the average Nusselt number (Nua) were proposed for all hybrid nanofluids, taking into account PPI, porosity, and Reynolds numbers as variables. Finally, the optimum values of Nua for all hybrid nanofluids were determined, providing valuable insights for optimizing the heat transfer performance in this configuration.

مطالعه عددی عملکرد ترموهیدرولیکی یک کانال موج‌دار با فوم فلزی و نانوسیال‌های هیبریدی
چکیده [English]
در این مطالعه، یک طراحی نوآورانه برای افزایش انتقال حرارت در یک کانال با فوم فلزی، دیواره‌های موج‌دار، و نانوسیال‌های هیبریدی پیشنهاد شد. تجزیه و تحلیل عددی نانوسیال‌های هیبریدی (MWCNTs+TiO2) با محلول DW (آب تقطیر شده) به عنوان مایع پایه در یک کانال با سطح موج مثلثی و فوم فلزی باز انجام شد. غلظت‌های جرمی نانوسیال‌های هیبریدی (ترکیبی از DW و MWCNTs+TiO2) به مقادیر 0.025٪، 0.05٪ و 0.075٪ در نظر گرفته شدند. تأثیرات تخلخل فوم فلزی و چگالی منافذ (PPI)، همچنین اعداد رینولدز مختلف (در بازه 7000 تا 13000) بر عملکرد حرارتی مورد بررسی قرار گرفتند. نتایج نشان داد که افزایش انتقال حرارت با فوم فلزی برای همه نانوسیال‌های هیبریدی به میزان 130٪ افزایش یافت. علاوه بر این، افزایش انتقال حرارت در فوم فلزی با تخلخل 0.9، 9.8٪ بیشتر از فوم فلزی با تخلخل 0.99 بود. به علاوه، رابطه‌های چندجمله‌ای برای میانگین عدد ناسلت متوسط برای همه نانوسیال‌های هیبریدی با متغیرهای مستقل PPI، تخلخل، و اعداد رینولدز ارائه شدند. در نهایت، مقادیر بهینه برای ناسلت متوسط برای همه نانوسیال‌های هیبریدی تعیین شدند.
