Hybrid Fluid

Nanofluids are suspensions of nanoparticles in fluids that show significant enhancement of their properties at modest nanoparticles concentrations. Nanofluids is about to understand their behavior so that they can be utilized where straight heat transfer enhancement is paramount as in many industrial applications, nuclear reactors, transportation, electronics as well as biomedicine and food. Nanofluids act as a smart fluid, where heat transfer can be reduced or enhanced.

Nanofluids are dilute liquid suspensions of nanoparticles with at least one of their principal dimensions smaller than 100 nm. Nanofluids have been found to possess enhanced thermo physical properties such as thermal conductivity, thermal diffusivity, viscosity and convective heat transfer coefficients compared to those of base fluids like oil or water.

Advanced electronic devices face thermal management challenges from the high level of heat generation and the reduction of available surface area for heat removal. So, the reliable thermal management system is vital for the smooth operation of the advanced electronic devices. Nanofluids with higher thermal conductivities are predicated convective heat transfer coefficients compared to those of base fluids. Recent researches illustrated that nanofluids could increase the heat transfer coefficient by increasing the thermal conductivity of a coolant.

Liquids and disordered (glassy) materials are very important materials in their own right, and they also play a vital role in many natural and industrial processes. As a classic example of this, water and aqueous solutions are essential ingredients for life, but are still a challenge for us to understand even at the most fundamental level. Control of processes such as solvation and dissolution is key to the many areas that rely on nanoparticles in solution, while liquids that are confined to very small pores or surfaces often exhibit properties that are remarkably different from those of the bulk.

Nanofluids are suspensions of nanoparticles in fluids that show significant enhancement of their properties at modest nanoparticles concentrations. Engine oils, automatic transmission fluids, coolants, lubricants, and other synthetic high-temperature heat transfer fluids found in conventional truck thermal systems—radiators, engines, heating, ventilation and air-conditioning (HVAC)—have inherently poor heat transfer properties. These could benefit from the high thermal conductivity offered by Alumina CNT nanofluids that resulted from addition of nanoparticles.
