Thermal transport in nanofluids

nanofluids in comparison to microfluids (of micro-sized particles) have been researched and it is found that nanofluids possess longer suspension time, higher thermal conductivity and are more energy efficient. Improving thermal transport properties of nanofluids has been claimed to be vital 2.1. Effective thermal conductivity of nanofluid Jang and Choi's heat transport theory 26 is adopted to describe the effective thermal conductivity of nanofluids, k eff.Jang and Choi assumed that the Reynolds number, Re, for nanoparticles is greater than unity and the Prandtl number, Pr, is approximately 10. Thermal conductivity enhancement in nanofluids, which are liquids containing suspended nanoparticles, has been attributed to localized convection arising from the nanoparticles' Brownian motion.

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. This thesis is constructed around the topic of thermal transport in nanofluids, with special emphasis of boiling heat transfer. Nanofluids boiling, as it is popularly known, have been researched nearly for two decades.

However, the hypothesis of thermal transport enhancement due to Brownian motion is being challenged [26–28]. The recent experimental and theoretical investigation strongly suggests that the nanoparticle aggregation (clusters) plays a significant role in the thermal transport in nanofluids.

Nanofluids have been proposed as a promising candidate for advanced heat transfer fluids in a variety of important engineering applications ranging from energy storage and electronics cooling to thermal processing of materials. We have calculated thermal conductivity of alumina nanofluids (with water and ethylene glycol as base fluids) using temperature as well as concentration-dependent viscosity, η. The temperature profile of η is obtained using Gaussian fit to the available experimental data. In the model, the interfacial resistance effects are incorporated through a phenomenological parameter α. The micro The thermal transport . properties of nanofluids, including thermal conductivity, viscosity, heat capacity and heat . transfer coefficient in convective environment were characterized and modeled.
