Summary: Turbulent forced convective flow of hybrid and single nanofluids in a conical diffuser is numerically investigated. The impact of using theoretical and experimental correlations for dynamic viscosity and thermal conductivity on the heat transfer is studied. Addition of TiO2 nanoparticles decreases the heat transfer inside the diffuser, whereas addition of TiO2-SiO2 nanoparticles either enhances or decreases the heat transfer rate. The Gene Expression Programming model accurately evaluates the relationship between the Nusselt number, Reynolds number, and nanoparticle concentration.

Summary: Metal foams are commonly used in enhanced heat transfer studies due to their large specific surface areas. Modified metal foams with gradient structures are preferred to reduce high pressure drop. A computational fluid dynamics analysis was conducted to investigate the forced convective heat transfer of metal foam samples with uniform and gradient structures. The gradient metal foam showed improved overall heat transfer performance when arranged from small to large porosity, and the gradient structure was better than the uniform structure at a given porosity value.

Summary: This study investigates the flow characteristics of ternary-hybrid nanofluids and their influence under temperature difference, nonlinear thermal radiation, and partial slip. The results show that partial slip reduces the friction at the wall, with the lowest decreasing rate observed in free convection. When induced by mixed convection, the increased motion of the three types of nanoparticles leads to optimal mass and heat transfer rates.

Summary: In a Taylor-Couette turbulent flow, we found that finite-size particles increase the drag of the system regardless of their aspect ratios. As the Reynolds number, Re, increases, the overall drag of the system also increases, in line with existing literature. The distribution of particles becomes more uniform with increasing Re, due to higher turbulence intensity and more pronounced finite-size effects.

Summary: In this study, pure and transition metal ions (Cu)-doped V2O5 nanosheets were synthesized and investigated as photocatalysts for the degradation of organic pollutants. The doped nanosheets showed improved efficiency for degrading methyl blue and rhodamine B under visible light. The incorporation of Cu dopant ions improved catalytic efficacy by separating charge carriers and facilitating their movement. The smaller crystalline size and increased specific surface area of the doped nanosheets also enhanced their photocatalytic activity.

Summary: In this study, a comprehensive model named Takayanagi is proposed to describe the gas performance of tubular filler contained mixed matrix membrane (MMMs) by considering interfacial morphology. The model includes interphase thickness, interphase permeability, and percolation threshold concept to accurately describe the MMM performance. It can also estimate the maximum separation potential of tubular filler. Polyvinylidene fluoride based MMMs containing pristine and acid modified multiwalled carbon nanotube are fabricated and characterized to validate the proposed model. The interphase morphology and contribution of carbon nanotubes in gas permeability are interpreted in details by the model.

Summary: Inorganic salts can disrupt the osmotic balance and cause harm to aquatic organisms. Osmotic membrane distillation (OMD) is an effective technique for recovering inorganic salts from wastewater. A computational fluid dynamics model was developed to study the recovery of sodium carbonate through OMD. The results showed that increasing the osmotic solution concentration significantly increased the water flux, while the flow rates of the feed solution and osmotic solution had little effect on the flux.
