دانلود مقاله مروری بر تحقیقات درباره راههای افزایش انتقال حرارت در یک لوله حاوی نانوسیالات تحت شرط مرزی شار حرارتی ثابت Heat transfer augmentation in a tube using nanofluids under constant heat flux boundary condition: A review
In the last few decades, research on nanofluids has increased rapidly. Traditional heat transfer fluids with
order of nanometer sized particles (1–100 nm) suspended in them are termed as nanofluids. Nanofluids
have been proved as better heat transfer fluids despite of various contradictions in results by different
research groups. The aim of this article is to review and summarize the recent experimental and theoretical
studies on convective heat transfer in heat exchangers using constant heat flux boundary condition.
The use of different types of nanoparticles with different base fluids by different research groups has been
presented and compared. Further an overview of experimental results about heat transfer abilities of
hybrid nanofluids from available literature sources is also presented. Finally, the challenges and future
directions in which research can be further progress are discussed

در این مقاله دربارۀ کاربردهای نانوسیالات در دستگاههای انتقال حرارت صحبت شده است.
This paper presents a critical review of heat transfer applications of nanofluids. The effects of nanoparticle
concentration, size, shape, and nanofluid flow rate on Nusselt number, heat transfer coefficient, thermal conductivity,
thermal resistance, friction factor and pressure drop from numerous studies reported recently are
presented. Effects of various geometric parameters on heat transfer enhancement of system using nanofluids
have also been reviewed. Heat transfer devices covered in this paper include radiators, circular tube heat exchangers,
plate heat exchangers, shell and tube heat exchangers and heat sinks. Various correlations used for
experimental validation or developed in reviewed studies are also compiled, compared and analyzed. The pros
and cons associated to the applications of nanofluids in heat transfer devices are presented in details to determine
the future direction of research in this arena.
