Review on Nano-Fluids Applications and Heat Transfer Enhancement Techniques in Different Enclosures

Abstract

Nano-fluid applications span such a broad range of topics in the practical field that they demand their own review articles. In this review paper, the use of magnetic fields, porous media, and Nano-fluids in different heat transfer applications is discussed mainly in the solar thermal field. It has been proven that the employment of these techniques provides significant enhancement results for convective flows especially when they are combined, also the mathematical equations used to model this type of flow are summarized. In addition, different studies reported that the geometrical parameters of the enclosures can also effect the flow. In this context, recently scholars maintained many investigations on complex shaped cavities and their impact on heat transfer. These studies showed promising results for the use of this type of geometries especially for the trapezoidal ones. As reviewed in this paper, trapezoidal geometries and their properties strongly effect the convective flow in a great way leading to considerable enhancement. Overall, this review aims to present an insightful vision on different heat transfer improvement techniques and values the use of these methods in trapezoidal geometries for solar heat transfer applications.

Hybrid-nanofluid magneto-convective flow and porous media contribution to entropy generation

“…Since the dawn of time, improving and controlling the performance of systems and structures needing thermal transfer has been considered to be critical, and numerous approaches have been established to reduce high energy consumption due to heat losses (Mebarek-Oudina and Chabani, 2023; Rathore and Shukla, 2019; Zafar et al , 2021; Mebarek-Oudina et al , 2023a). Hence, in fluid dynamics related problems, the following enhancement methods were suggested including: nanofluids integrated into thermal systems in several ways due to the exceptional thermo-physical characteristics of nanoparticles to enhance the behaviour of the classical heat transfer fluids, porous medium and magnetic fields (Huminic and Huminic, 2020; Marcato et al , 2022; Mebarek-Oudina and Chabani, 2022; Said et al , 2022). In this context, many studies were launched to examine the concept and employment of magnetic nanofluids in porous cavities.…”

Three-Dimensional Analysis of the Thermal Behavior of Alumina-Water Nanofluid Inside Hexagonal and Octagonal Enclosed Domain

“…In the last decays the heat transferred by free convection inside enclosures were gained a great interest because of its wide engineering applications. Different configurations of enclosures and working fluids are investigated numerically and experimentally [1][2][3][4][5]. Different geometries of the cavities; cubical or non-cubical are discovered [5][6][7][8].…”
