The effects of nanoparticle size, concentration, and state of aggregation are examined. A thermal transport analysis in nanofluids for multiple shapes of tiny particles in the presence of Lorentz forces and heat generation/absorption is reported. The flow is carried out over an unsteady thin slit. The effects of the main flow parameters on the velocity and temperature behavior are illustrated.

Engineering Nanofluids for Heat Transfer - AVHANDLINGAR.SE

Research has shown that nanofluids, in comparison to base fluids like water/oil, possess enhanced thermophysical properties such as thermal conductivity and convective heat The reasons why nanofluids possess enhanced thermal properties are as follows [1]: 1) The suspended nanoparticles increase the relative surface area of the fluid. A thermal transport analysis in nanofluids for multiple shapes of tiny particles in the presence of Lorentz forces and heat generation/absorption is reported. The flow is carried out over an unsteady thin slit.
