چکیده

در این مقاله اثرات افزودن نانوذرات به سیال عامل آب جهت خنک کاری موتور خودرو مورد بررسی قرار میگیرد. برای این منظور یک مدل سه بعدی CFD برای شبیه سازی جریان و انتقال حرارت در موتور خودرو یکبار با سیال عامل آب خالص و بار دیگر با نانوسیال مورد ارزیابی قرار گرفته است. تغییرات میزان انتقال حرارت موثر در خنک کاری خودرو با استفاده از نانوسیال TiO2 مورد بررسی قرار میگیرد. در نهایت نشان داده می شود که استفاده از نانوسیال 1% حجمی TiO2 قابلیت افزایش میزان انتقال حرارت را تا 37% بیشتر از سیال عامل آب خالص دارا است.
