Summary: This paper extracted the thermal conductivity of cerium oxide/ethylene glycol nanofluid for different temperatures and volume fractions of nanoparticles, and predicted it using Artificial Neural Network (ANN) and fitting method. The experiments showed an increase in the thermal conductivity ratio of the nanofluid with increasing volume fraction and temperature. It was observed that the rate of increase in thermal conductivity at high temperatures is higher than at low temperatures. The ANN proved to be highly effective in predicting the thermal behavior of the nanofluid.

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: The study focused on the thermal conductivity enhancement of hybrid nanofluid (HN) and dihybrid nanofluid (DHN) by dispersing titanium dioxide nanoparticles and multi-walled carbon nanotubes. Experimental results showed a 30.83% increase in thermal conductivity when MWCNT was added, compared to HN. X-ray diffraction analysis and microscopy were used to analyze the phase and microstructure. Novel correlations were calculated for HN and DHN, and an artificial neural network was modeled for predicting thermal behavior at various volume fractions and temperatures.

Summary: Glycerol, a co-product in the biodiesel process, can be used as a raw material in a biorefinery scheme. Studies have been conducted to selectively reduce and oxidize glycerol, as well as steam reform it, to produce valuable chemicals and energetic compounds. The integration of these processes into a biorefinery framework has been demonstrated. The conversion of glycerol to various compounds such as propylene glycol, ethylene glycol, hydrogen, dihydroxyacetone, lactic acid, syngas, carbon dioxide, and methane shows the potential of utilizing glycerol in expanding biorefinery schemes.

Summary: Experimental research was conducted on the heat transfer, entropy generation, and exergy efficiency of ethylene glycol (EG) based nanodiamond (ND) nanofluids flowing in a circular tube. The study showed that the heat transfer coefficients of ND nanofluids were higher than that of the base fluid, and the improvement in entropy generation and exergy efficiency depended on the volume concentration of the nanofluid and Reynolds number.

Summary: Permeability and capillary performance, which are important parameters for heat pipes, are affected by the particle size and geometry of copper powder. The porosity and capillary performance of sintered porous wicks made from different-sized spherical and dendritic Cu powders were studied. The results showed that both types of copper powder had higher porosity and capillary performance with larger particle size, due to increased connectivity between internal pores. The dendritic powder exhibited superior capillary efficiency and porosity compared to the spherical powder. A model was also proposed to predict the capillary performance and permeability of sintered porous copper.
