challenges facing many diverse industries, including microelectronics, transportation, solid-state lighting, and manufacturing. Technological developments such as microelectronic devices with smaller (sub-100 nm) features and faster (multi-gigahertz) operating speeds, higher-power engines, and brighter optical devices are driving increased thermal loads, requiring advances in cooling. The conve...

For more than 20 years, the use of nanofluids to enhance heat transfer in microchannel sinks (MCHSs) has been subject a large number scientific articles. Despite great potentialities reported several works, presence controversial results and lack understanding enhancement mechanisms prevent further advancement as coolants. This article reviews literature focused on aspects that have role within...

The design and development of a photovoltaic thermal (PVT) collector were developed in this study, electrical efficiency assessed. To improve system performance, two types coolants employed, liquid liquid-based MnO nanofluid. Flow rates ranging from 1 to 4 liters per minute (LPM) for the interval 1.0 LPM together with 0.1% concentration manganese oxide (MnO) Various parametric investigations, i...

Heat transfer fluids are a dynamic factor that affects the costs and size of heat exchangers. However, low thermal properties accessible coolants like water oils place setback on growth to attain high-performance cooling. The paper presents numerical analysis comparative study characteristics Al 2 O 3 , CuO, AlN, SiC water-based nanofluids in square cavity. cavity is surrounded by hot moving ho...

Abstract In this article, analysis of average Nusselt number (Nuavg), which indicates the heat removal from battery pack cooled by flowing fluid is carried out considering coupled transfer condition at and coolant interface. Five categories coolant, mainly gases, common oils, thermal nanofluids, liquid metals, are selected. each category, five fluids (having different Prandtl Pr) selected passe...

Nanofluids are suspended nano-sized particles in a base fluid. With increasing demand for more high efficiency thermal systems, nanofluids seem to be a promising option for researchers. As a result, numerous investigations have been undertaken to understand the behaviors of nanofluids. Since their discovery, the thermo-physical properties of nanofluids have been under intense research. Inadequa...

an empirical electrical conductivity assessment of nanofluids comprising cuo nanoparticles water-based in different concentrations, particles size and various temperatures of nanofluids has been carried out in this paper. these experimentations have been done in deionized water with nanoparticles sizes such as 89, 95, 100 and 112 nm and concentrations of 0.12 g/l, 0.14 g/l, 0.16 g/l and 0.18 g/...
