Thermal transport in nanofluids

Masuda et al.18 reported a 30% increase in the thermal conductivity of water with the addition of 4.3 vol.% Al 2 O 3 nanoparticles. Thermal transport in Nanofluids Hongwei Sun , Mechanical Engineering Nanofluids is an emerging new class of thermal fluids for future thermal transport and energy saving due to its unique characteristics such as large surface-to-volume ratio, strong Brownian motion, low particle loading (<5%) and high thermal conductivity. Recent experiments on nanofluids have indicated significant increases in thermal conductivity compared with liquids without nanoparticles or larger particles, strong temperature dependence of Early experimental studies of the thermal transport properties of nanofluids focused on changes in properties created by high concentrations of oxide nanoparticles. 1Masuda et al.8reported a 30% increase in the thermal conductivity of water with the addition of 4.3 vol.% Al 2O Nanofluids, which are typically categorized as colloidal suspension of 1-100 nm nanoparticles in fluids, have been extensively reported to have superior heat transfer properties, such as higher Recent experiments on nanofluids have indicated significant increases in thermal conductivity compared with liquids without nanoparticles or larger particles, strong temperature dependence of thermal conductivity, and significant increases in critical heat flux in boiling heat transfer. One of the most extensively considered factor on thermal transport performance, the key variable for nanofluids’ improvement, is the nanostructures concentration dispersed within conventional fluids. Filler concentration has been stated by weight and volume percentages in research, reports, papers and patents.

Heat Transfer Enhancement with Nanofluids - Vincenzo

Although various conjectures have been proposed to explain the abnormal increase in thermal conductivity of nanofluids, the detailed mechanism has not been fully understood and explained. The main reason is due to the lack of knowledge of the most fundamental factor governing the mechanisms such as Brownian motion, liquid layering, phonon transport, surface chemical effects, and … 2007-10-01 Nanoparticles can improve the thermal properties of fluids in a remarkable manner. Despite a plethora of experimental and theoretical studies, the underlying physics of heat transport in nanofluids is not yet well understood.
