TL;DR: In this paper, the role of porous media in enhancing heat transfer performance of nanofluids and hybrid nanoparticles when flow occurs through different geometries has been discussed and the external magnetic field has been explored.
Abstract: Heat transport finds use in several applications including heat exchangers, marine units, food processing units, oil and gas industries, petroleum industries and so on. By providing a large surface area and irregular motion in flow, made possible by porous media and enhances the thermal efficiency. The addition of a single type of nanosized particles in the base fluid gives rise to nanofluids. It tends to have higher thermal conductivity than the base fluid. However, currently hybrid nanofluids are introduced to overcome the disadvantages associated with nanofluids such as lower chemical stability, lower corrosion-resistant and so on. Hybrid nanofluids consist of dissimilar nanoparticles. Here, the heat transfer performance of nanofluids and hybrid nanofluids which flow through porous media is discussed. In addition, the role of the external magnetic field on the heat transfer performance of nanofluids with porous media is also explored. The relation between important parameters like Darcy number, porosity, Hartmann number, Reynolds number, Biot number and heat transfer performance of fluids with porous media is duly discussed. This chapter focuses on the role of porous media in enhancing heat transfer performance of nanofluids and hybrid nanofluids when flow occurs through different geometries.

TL;DR: A review of the progress made in the area of nanofluids preparation and applications in various heat transfer devices such as solar collectors, heat exchangers, refrigeration systems, radiators, thermal storage systems and electronic cooling is presented in this paper.
Abstract: The field of nanofluids has received interesting attention since the concept of dispersing nanoscaled particles into a fluid was first introduced in the later part of the twentieth century This is evident from the increased number of studies related to nanofluids published annually The increasing attention on nanofluids is primarily due to their enhanced thermophysical properties and their ability to be incorporated into a wide range of thermal applications ranging from enhancing the effectiveness of heat exchangers used in industries to solar energy harvesting for renewable energy production Owing to the increasing number of studies relating to nanofluids, there is a need for a holistic review of the progress and steps taken in 2019 concerning their application in heat transfer devices This review takes a retrospective look at the year 2019 by reviewing the progress made in the area of nanofluids preparation and the applications of nanofluids in various heat transfer devices such as solar collectors, heat exchangers, refrigeration systems, radiators, thermal storage systems and electronic cooling This review aims to update readers on recent progress while also highlighting the challenges and future of nanofluids as the next-generation heat transfer fluids Finally, a conclusion on the merits and demerits of nanofluids is presented along with recommendations for future studies that would mobilise the rapid commercialisation of nanofluids

TL;DR: In this article, the role of altering Lorentz force on nanomaterial flowing within two discs and its thermal behavior is surveyed, and it is concluded that growth of S guides to reduce in Nu and similar tendency can be seen for A because of reduction of temperature gradient with rise of amount of inlet velocity.
Abstract: Current investigation is surveyed the role of altering Lorentz force on nanomaterial flowing within two discs and its thermal behavior. The basis governing formula convert to ODEs based on applying two phase model. Based on acquired outcomes, there is direct correlation between Nu and Nt. Invoking the impact of S, it is concluded that growth of S guides to reduce in Nu and similar tendency can be seen for A because of reduction of temperature gradient with rise of amount of inlet velocity. Impermeable wall leads to stronger influence of Nt and outcomes reveal that Nu has direct relationship with Nt. Reducing impact of A declines with rise of Nt which means that thermophoresis act against permeability.
