Impact of an effective Prandtl number model on the flow of nanofluids past an oblique stagnation point on a convective surface

Zafar Mahmood et al.

Summary: By using nano-particles, the convective heat transfer capability of a stretched surface can be improved. This study proposes an effective Prandtl number model to explore the two-dimensional oblique stagnation point flow of gamma Al2O3-H2O and gamma Al2O3-C2H6O2 nanofluids over a convective stretching surface. Results show that as the volume fraction of nanoparticles increases, the fluid flow and velocity increase, while they both decrease with the increase of the stretching ratio parameter. In terms of heat transfer rate, the gamma Al2O3-C2H6O2 nanofluid outperforms the gamma Al2O3-H2O nanofluid.

Numerical analysis of ternary hybrid nanofluid flow over a stagnation region of stretching/shrinking curved surface with suction and Lorentz force

Zafar Mahmood et al.

Summary: This study analyzes the potential practical applications of ternary hybrid nanofluid in stagnation point flow. Numerical solutions are obtained by converting governing PDEs into ODEs and using the MATHEMATICA program. The results show that velocity improves with the presence of magnetic field and suction, while temperature increases with nanoparticle volume fraction and heat source/sink, but decreases with suction and curvature parameters. The findings provide valuable insights for adjusting relevant parameters in practical applications.

Mathematical investigation of nanoparticle aggregation and heat transfer on mixed convective stagnation point flow of nanofluid over extendable vertical Riga plate

Zafar Mahmood et al.

Summary: The study evaluates the effects of nanoparticle aggregation on mixed convective stagnation point flow and porous media utilizing a permeable stretched vertical Riga plate. The aggregation of nanoparticles was evaluated with modified versions of the Krieger-Dougherty and Maxwell-Bruggeman models. Numerical solutions were obtained using the Runge-Kutta (RK-IV) with shooting technique in Mathematica. The results showed that aggregation models provided more accurate velocity and skin fraction profiles than homogeneous models.

Mixed convective flow of hybrid nanofluid over a heated stretching disk with zero-mass flux using the modified Buongiorno model

Bilal Ali et al.

Summary: This study investigates the mixed convective stagnation-point flow of a Al2O3-Cu/H2O hybrid nanofluid towards a stretched disc with a convective boundary and zero mass flux condition, taking into account mass suction and viscous dissipation effects. The flow, heat, and mass transfer characteristics are analyzed using the Buongiorno model and the Devi and Devi model. The results show good agreement with previous studies, and the velocity and temperature profiles increase with nanoparticle volume fraction and mixed convection parameter.

Various nanoparticle shapes and quadratic velocity impacts on entropy generation and MHD flow over a stretching sheet with joule heating

Khadija Rafique et al.

Summary: The research aimed to investigate the impact of different shapes of nanoparticles on the entropy production of a water-alumina nanofluid. The results showed that the wall shear stress increases by almost 6.3% for increases in the volume fraction of nanoparticles from 0% to 2% and by 12.6% for increases from 0% to 4% in the region behind a stretching sheet. When the magnetic effect accounts for roughly 5 percent of the boundary layer flow, there is an approximately 16.4 percent increase in the rate of convective heat transfer. The frictional force and thermal entropy produced by nanofluids with blade-, brick-, and Os-shaped NPs were lower than that produced by nanofluids with platelet-shaped NPs. On the cold fluid side, the nanofluid with Os-shaped NPs develops thermal entropy at a faster rate than those with brick-, blade-, cylinder-, and platelet-shaped NPs.

Impact of nanoparticle shape on entropy production of nanofluid over permeable MHD stretching sheet at quadratic velocity and viscous dissipation

Khadija Rafique et al.

Summary: The study investigates the impact of NP shape on the entropy produced by Al2O3 - H2O nanofluid in a permeable MHD stretching sheet. Different NP forms (oblate spheroid, platelet, blade, brick, and cylinder) were considered, with H2O as the cold fluid and Al2O3 - H2O nanofluid as the hot fluid. The research finds that incorporating magnetic effect and increasing the phi leads to an increase in wall shear stress and convective heat transfer. Additionally, the Os-shaped NP nanofluid exhibits a greater increase in thermal entropy on the cold fluid side compared to other NP shapes.

Basim M. Makhdoum et al.

Summary: This study examines the performance of a TiO2 - C2H6O2 nanofluid in unsteady stagnation-point flow by a shrinking horizontal cylinder. The findings indicate that increasing suction settings can improve heat transfer operation and various factors such as magnetic field, nanoparticle volume fraction, curvature, and Eckert number also affect heat transfer rate. Additionally, the presence of aggregation affects the velocity and temperature profiles.

Summary: This paper presents a new mathematical model for enhancing heat transfer using tri-hybrid nanofluids.

Results show that the Nusselt number of the nanofluid, hybrid nanofluid, and tri-hybrid nanofluid are improved by 9.8%, 19.85%, and 44.04% respectively compared to ordinary fluid.

Summary: This study investigates the heat transfer phenomenon in nanofluids containing carbon nanotubes with different lengths and radii. The effects of viscosity and joule heating on motion are also examined.

The results show that the addition of carbon nanotubes increases the rate of heat transfer. The proposed numerical model is validated through comparison with previously published results.

Summary: This paper investigates the flow of a hybrid nanofluid towards a stagnation point on an exponentially stretching/shrinking vertical sheet with buoyancy effects. The authors found that the heat transfer rate is higher for the Al2O3-Cu/water hybrid nanofluid compared to Cu/water nanofluid, and observed non-uniqueness of solutions for certain physical parameters. Additionally, bifurcation of solutions was noticed in the downward buoyant force and shrinking regions.
