چکیده

در این پژوهش آزمایشگاهی به بررسی افزایش ضریب انتقال حرارت در جوشش استخری نانوسیال با ذرات مس اکسید (CuO) با استفاده ازروش‌های تغییر pH و امواج فراصوت پرداخته شده است. نانوذرات موجب افزایش ضریب انتقال حرارت سیال پایه در فرآیند جوشش شده‌ اما این مواد به‌علت عدم پایداری با افزایش دما و زمان، موجب رسوب بر سطح گرم‌کن و در نهایت موجب کاهش ضریب انتقال حرارت می‌شوند. در نتیجه لازم است که غلظت بهینه نانوذرات در سیال به‌دست آید تا کمترین مقدار رسوبات تشکیل شود. بنابراین استفاده از روش‌هایی که منجر به کاهش رسوب نانوذرات برروی سطح شوند، مانند افزایش پایداری نانوذرات و استفاده از غلظت بهینه، می‌تواند ضریب انتقال حرارت را افزایش دهد. در این کار از دو روش پایداری نانوذرات در محلول یعنی تغییر pH (5/9، 10 و 5/10) و تابش امواج فراصوت (با توان‌های 25، 50 و 75% از توان دستگاه فراصوت (kW 2/1)) استفاده شده است. نتایج کار به‌خوبی نشان داد که در غلظت wt.% 125/0 از محلول نانوسیال، بیشترین مقدار ضریب انتقال حرارت با تابش امواج فراصوت ( 50% توان) برابر 48/37% و در تغییر اسیدیته محلول (10=pH) برابر با 68/22% حاصل شد.

چکیده [English]

In this study, the effects of pH and ultrasonic waves on the performance and stability of CuO have been studied. The CuO nanofluid (deionized water-based) was used to increase the boiling heat transfer coefficient. Boiling heat transfer coefficient of fluid increased by the addition of nanoparticles into the fluid, but due to the instability of nanoparticles by increasing temperature and time, nanoparticles were precipitated on the heat transfer surface. Therefore, it led to a reduction in the boiling heat transfer coefficient. Moreover, it is necessary to obtain the optimal concentration of nanoparticles in the fluid to determine the minimum amount of deposition. The use of methods to reduce the deposition of nanoparticles such as increasing the stability of nanoparticles and also an optimal concentration made an increase in heat transfer coefficient. To overcome this challenge, two conventional methods were employed including pH change (9.5, 10 and 10.5) and ultrasonic radiation (with 25%, 50%, and 75% of power). The results indicated that the maximum enhancements of boiling heat transfer coefficient were achieved at nanoparticles concentration of 0.125% under ultrasonic radiation with 50% power and the pH value of 10 as average of 37.48% and 22.68%, respectively.
