TL;DR: In this article, a corrugated plate heat exchanger in solar energy systems is used to investigate heat transfer and fluid flow characteristics of various nanofluids by adding various nanoparticles (Al2O3-30nm, SiC-40nm, CuO-30 nm and Fe3O4-25nm) into the base fluid.

TL;DR: In this article, a 4:6 mixture of ethylene glycol and deionized water was used as the base liquid for an electric heater to investigate the heat transfer performance of different magnetic fields.

TL;DR: In this paper, the effect of magnetic field strength and distribution on the performance of a plate heat exchanger filled with ferrofluids was investigated and the results indicated that with a vertical arrangement of two magnets side by side outside the sidewalls, 21.8% increase in average Nusselt number and 10.0% reduction in average pressure drop were achieved compared to the cases without a magnetic field.

TL;DR: In this paper, the phase change latent heat, viscosity, and thermal conductivity of the nanocomposite PCMs were measured based on analyses of melting and freezing curves and infrared thermal imaging tests, and the effects of heating power and fan power on heat transfer characteristics of the heat pipe with PCMs as the cooling system.

Abstract: Commonly, heat transfer performance of a nanofluid is enhanced by increasing the mass fraction of nanoparticles due to an improvement of the thermo-physical properties. However, increasing the numb...
