چکیده
در این تحقیق، یک نمونۀ سه بعدی از یک رادیاتور توسط نرم افزار SolidWorks مدلسازی و اثرات افزوده شدن نانوذرات به صورت هیبرید به سیال پایۀ خنک کننده از نظر خواص ترموفیزیکی نانوسیال و همچنین عملکرد حرارتی رادیاتور به صورت مدلسازی و آزمون تجربی بررسی شد. نانوذرات استفاده شده در این تحقیق شامل Al2O3 و SiC در چهار سطح مختلف جرمیِ SiC1% +Al2O34% ، SiC2% +Al2O33% ، SiC3% +Al2O32% و SiC4% +Al2O31% تعریف و مدلسازی شد. بررسی نتایج نشان داد که افزوده شدن نانوذرات به سیال سبب افزایش ویسکوزیته، چگالی و ضریب انتقال حرارت نسبت به سیال پایه شده که به ازای نانوسیال SiC1% +Al2O34%، بیشینۀ چگالی و ضریب انتقال حرارت و بهترین عملکرد برای خنک کاری سیال مشاهده می شود ولی مقدار ویسکوزیته بین نمونه ‌های مختلف نانوسیال تفاوتی ندارد. همچنین نتایج نشان داد که افزودن نانوذرات و ایجاد نانوسیال در طراحی رادیاتور منجر به تثبیت دمای خروجی آن می شود که نمایانگر بهبود چشمگیر در کارکرد حرارتی رادیاتور است. نتایج آزمون‌های تجربی نیز نشان داد که با افزوده شدن نانوذره به سیال پایه، دمای سیال ورودی به رادیاتور، دمای سیال خروجی از رادیاتور و دمای هوای عبوری از روی پره‌ها به ترتیب افزایش، کاهش و افزایش می یابد.

چکیده English

In this research, a three-dimensional model of a radiator was created using SolidWorks software. The effects of adding hybrid nanoparticles to the coolant base fluid on the thermo-physical properties of the nanofluid and the radiator thermal function were investigated through modeling and experimentation. The nanoparticles used in this research consist of Al2O3 and SiC in four various mass levels, including 1%Al2O3+4%SiC, 2%Al2O3+3%SiC, 3%Al2O3+2%SiC, and 4%Al2O3+1%SiC, which were defined and modeled. The results showed that adding the nanoparticles to the fluid causes an increase in viscosity, density, and heat transfer coefficient in the base fluid such that for the hynanofluid 4%Al2O3+1%SiC, the maximum density, heat transfer coefficient, and the best function is seen for fluid cooling, but the viscosity values among various samples do not differ considerably. Also, the results showed that adding the nanoparticles and creating the nanofluid in the radiator design causes consistency in the radiator output temperature, which represents a significant improvement in the radiator's thermal function. The experimental results showed that by adding nanoparticles to the base fluid, the temperatures of the fluids entering and pouring out of the radiator, and the temperature of the air passing over the radiator fins increase, decrease, and increase, respectively.
