Journal ArticleDOI
TL;DR: In this article, a magnetic nanocomposite with magnetite (Fe 3 O 4 ) nanoparticles has been synthesized successfully by in-situ and chemical reduction of Fe 3+ and Fe 2+ cations on the acid treated-ND surface by using sodium hydroxide as a reducing agent.

TL;DR: In this paper, a review summarizes numerous researches on two topics; the first section focuses on studying the fluid flow and heat transfer behavior of different types of microtubes (MT) and microchannel (MC) at different orientations.
Abstract: Research on convective heat transfer on internal microtube and microchannel has been extensively conducted in the past decade. This review summarizes numerous researches on two topics; the first section focuses on studying the fluid flow and heat transfer behavior of different types of microtubes (MT) and microchannel (MC) at different orientations. The second section concentrates on nanofluids; its preparation, properties, behavior, and many others. The purpose of this article is to get a clear view and detailed summary of the influence of several parameters such as the geometrical specifications, boundary conditions, and type of fluids. The maximum Nusselt number is the main target of such research where correlation equations were developed in experimental and numerical studies are reported. The heat transfer enhancement of nanofluids along with the nanofluids preparation technique, types and shapes of nanoparticles, base fluids and additives, transport mechanisms, and stability of the suspension are also discussed.

Journal ArticleDOI
TL;DR: In this article, the authors found that the presence of three major characteristics enhanced critical heat flux (CHF): wettability, liquid spreadability and multi-scale geometry, and fabricated artificially modified surfaces with arrays of octagonal micro-posts, or ZnO nanorods, or both, and measured their performance in enhancing CHF.

Journal ArticleDOI
TL;DR: In this paper, a thin channelled copper water block of overall dimension 55 × 55 × 19 mm is used for the study. And the interface temperature of the water block is measured and a maximum reduction of 1.15°C is observed when nanofluid of 0.2% volume fraction is used as the working fluid compared to deionised water.
