Summary: In this study, the densities and viscosities of binary mixtures of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide, [bmim][NTf2], and ethylene glycol (EG) were experimentally measured. A first-order polynomial and Vogel-FulcherTammann equation were used to estimate the densities and viscosities of the mixtures, respectively. The excess molar volume, viscosity, and Gibbs energy of activation for viscous flow were calculated and fitted to the Redlich-Kister equation. The thermal expansion coefficients and partial and apparent molar volumes of [bmim][NTf2] and EG in their binary mixtures were also investigated.

Summary: This study investigates the impact of Solid Volume Fraction (SVF) and temperature on the dynamic viscosity of a hybrid antifreeze composed of MWCNTs and aluminum oxide. An Artificial Neural Network (ANN) is used to accurately predict viscosity based on input parameters. The findings show that Shear Rate (SR) and SVF have opposite effects on the viscosity of the nanofluid, while temperature has a smaller impact. The proposed ANN model outperforms other techniques in predicting viscosity. This research has important implications for the design of heat exchangers using nanofluids, particularly in portable devices.

Summary: This paper presents the experimental results of studying graphene particle suspensions in lubricating oil, ethylene glycol, and glycerol-based fluids. The viscosity of the graphene particles with different specific surface areas varies with the shear rate and temperature. The lubricating effect, i.e., a decrease in viscosity compared to the base fluid, is observed for concentrations below 0.4 mass% in lubricating oil and glycerol. The activation energy slightly decreases within the studied parameters (e.g., concentration below 1 mass% and temperature up to 80℃). The increase in viscosity with graphene volume fraction is more significant in ethylene glycol.

Theoretical simulation is conducted to analyze the correlation mechanism of the piston assembly. The research shows that the thermally-driven pump can greatly reduce power consumption and has potential for industrial applications.
