Silver/oil Nanofluids in Heat Exchanger An Experimental Study on Convective Heat Transfer

“…It was observed similar results for other temperatures. It obtained similar results with previous researches 5,9 . …”

“…For synthesis of Ag NPs, a number of synthesis approaches are available for example photochemical and chemical reactions, thermal decomposition, reduction in solution, electrochemical, sonochemical, microwave and also green synthesis 8 . Nanofluids are a suspension from nanoparticles smaller than 100 nm in size that dispersed in a base fluid 9 . They are a category of new heat transfer fluids that used in conventional heat transfer fluids.…”

“…They are a category of new heat transfer fluids that used in conventional heat transfer fluids. It is used usually two-step method to prepare them 9 .…”

“…Nanofluids can be considered as one of the most suitable and most effective choice for heat transfer. Small particles in the nanofluids reduce the corrosion, pressure drop and make the fluid more stable 9 . Today research on nanofluids has become widespread.…”

Thermotunable Terahertz Negative-Index Metamaterials with Dielectric Spheres Embedded in Semiconductor Host

“…Most of the MMs designs are constructed by the metallic elements, which incur many drawbacks such as high loss, very narrow bandwidth, and highly anisotropic. An alternative scheme was proposed based on the resonance in individual nonmagnetic dielectric scatterer with very high permittivity [11][12][13][14]. However, dielectrics with extremely high permittivity also suffer from large damping.…”
