Thermal-hydraulic performance of a nanofluid in a shell-and-tube heat exchanger equipped with new trapezoidal inclined baffles: Nanoparticle shape effect

Mehdi Bahiraei et al.

Summary: The study analyzed the influences of diverse shapes of nanoparticles on the thermal-hydraulic efficacy of a nanofluid containing boehmite nanoparticles in a shell and tube heat exchanger. Different particle shapes had varying effects on the heat transfer performance, with the nanofluid with platelet particles demonstrating the highest overall heat transfer coefficient. Additionally, the nanofluid with Os nanoparticles exhibited the greatest effectiveness compared to other nanoparticle suspensions with different shapes.

Insight into the Rheological Behavior of Hybrid Zinc Oxide and MWCNT Nanoparticles Dispersed in 10W40 Engine Oil: Experimental Study

Mohammad Hemmat Esfe et al.

Summary: The study investigates the rheological behavior of ZnO-MWCNT/10W40 nanofluid and proposes a mathematical relation to calculate the NF viscosity. Results show a direct relationship between dynamic viscosity and VF, and an inverse relationship with temperature and SR. Sensitivity analysis indicates that viscosity is primarily dependent on temperature.

Influence of base fluid, temperature, and concentration on the thermophysical properties of hybrid nanofluids of alumina-ferrofluid: experimental data, modeling through enhanced ANN, ANFIS, and curve fitting

S. O. Giwa et al.

Summary: The study investigated the suspension of hybrid nanoparticles in conventional fluids to improve the thermophysical properties of nanofluids, specifically focusing on the trio influence of volume concentration, base fluid, and temperature on the electrical conductivity and viscosity of hybrid alumina-ferrofluids. The results showed that an increase in volume concentration enhanced the viscosity and electrical conductivity of the hybrid alumina-ferrofluids, while a rise in temperature enhanced their electrical conductivity but detracted the viscosity. Additionally, DW-based hybrid alumina-ferrofluid exhibited lower viscosity and higher electrical conductivity compared to the EG-DW-based counterpart.

An experimental report and new correlation for estimating the dynamic viscosity of MWCNT(50)-ZnO(50)/SAE 50 as nano-lubricant

Mohammad Hemmat Esfe

Summary: This study experimentally investigated the viscosity and rheological behavior of SAE 50 engine oil containing MWCNT-ZnO nanoparticles. The results demonstrated non-Newtonian behavior in nano-oil, similar to non-Newtonian shear-thinning fluids. A new mathematical correlation was proposed to improve prediction accuracy and reduce costs in future studies.

Effect of transverse and parallel magnetic fields on thermal and thermo-hydraulic performances of ferro-nanofluid flow in trapezoidal microchannel heat sink

Mojtaba Sepehrnia et al.

Summary: This study investigates the thermal and thermo-hydraulic performances of ferro-nanofluids in a three-dimensional trapezoidal microchannel heat sink under different magnetic field orientations. Results show that the direction of the magnetic field significantly affects the thermohydraulic behavior, with Case III performing best in terms of thermal indicators but Case II being the best based on the performance evaluation criterion.

Optimization of Nano-Additive Characteristics to Improve the Efficiency of a Shell and Tube Thermal Energy Storage System Using a Hybrid Procedure: DOE, ANN, MCDM, MOO, and CFD Modeling

Mohammed Algarni et al.

Summary: The use of nano-enhanced phase change material (NePCM) in latent heat thermal energy storage (LHTES) systems significantly impacts melting/solidification duration and stored energy. This study utilized a hybrid approach involving design of experiments (DOE), computational fluid dynamics (CFD), artificial neural networks (ANNs), multi-objective optimization (MOO), and multi-criteria decision making (MCDM) to optimize nano-additives properties in a shell and tube LHTES system containing paraffin wax as a phase change material (PCM). Multiple optimization variables related to nano-additive properties were considered, with the primary goal of reducing melting duration and increasing total stored energy.

An experimental study on dynamic viscosity and thermal conductivity of water-Cu-SiO2-MWCNT ternary hybrid nanofluid and the development of practical correlations

Amin Dezfulizadeh et al.

Summary: This study experimentally investigated the dynamic viscosity and thermal conductivity of Cu-SiO2-MWCNT/water ternary hybrid nanofluid, proposing linear mathematical correlations for estimation. By combining metal and metal oxide nanoparticles with ternary polymers nanoparticles, a novel nanofluid was fabricated. Results showed that both thermal conductivity and dynamic viscosity were dependent on temperature and volume concentration, with the ternary hybrid nanofluid exhibiting significantly greater properties compared to mono and binary nanofluids.

Numerical simulation on heat transfer of nanofluid in conical spiral heat exchanger

Ali Davoudi et al.

Summary: The research article investigates the performance of a conical spiral heat exchanger with rectangular cross sections using two different nanofluids, Al2O3/water and CuO/water. It is found that increasing the nanofluid concentration enhances the secondary flow, increases pressure drop, decreases heat transfer rate, and reduces the figure of merit (FOM). The impact of nanoparticle concentration on these parameters is more significant for CuO compared to Al2O3 at lower concentrations, while the opposite is observed at higher concentrations.
