Rheological behaviour of IoNanofluids based on [emim][DCA] and [emim][TCM]

M. Hothar et al.

Summary: The viscosity of ionanofluids consisting of two ionic liquids and nanoparticles has been measured, and equations have been proposed to predict the temperature dependency of the liquid's viscosity. The pure ionic liquids were Newtonian fluids, while the ionanofluids showed a mixture of Newtonian and non-Newtonian behavior, with increasing viscosity at low shear rates and high temperatures. The accuracy of the prediction models needs improvement.

Ionanofluids with [C2mim][CH3SO3] ionic liquid and alumina nanoparticles: An experimental study on viscosity, specific heat and electrical conductivity

Elena Ionela Chereches et al.

Summary: This research experimentally studied the properties of 1-ethyl-3-methylimidazolium methanesulfonate ([C(2)mim][CH3SO3]) ionic liquid and its ionanofluids with Al2O3 nanoparticles of different mass concentrations, showing that viscosity and specific heat increase with nanoparticle concentration while electrical conductivity decreases. These new fluids have the potential to be alternative high temperature heat transfer fluids for solar applications.

From lab and up: superior and economic heat transfer performance of ionanofluids containing long carbon nanotubes and 1-ethyl-3-methylimidazolium thiocyanate

Bertrand Jozwiak et al.

Summary: This study investigated the heat transfer performance of ionanofluids composed of long multi-walled carbon nanotubes and an ionic liquid, showing that heat transfer is dominated by convection mechanisms. The amalgamation of these components was justified by a new thermo-economic efficiency-price index, demonstrating advantages in both thermophysical and economic aspects.
