Double-diffusive stagnation point flow over a vertical surface with thermal radiation: Assisting and opposing flows

Ammara Islam et al.

Summary: In various industrial processes, design engineers focus on ensuring efficient heat and mass transfer, such as in heating and cooling practices of solar water heaters, geothermal systems, metal extrusion, building insulation, electronics, turbines, aerodynamics, paper manufacturing, and glass fiber production. This study investigates the unsteady double-diffusive mixed convection flow of boundary layer nanofluids near a stagnation point, incorporating the effects of Brownian motion and thermophoresis using Buongiorno's model. By employing the local similarity method and suitable transformations, the non-linear partial differential equations are transformed into non-linear ordinary differential equations and solved numerically using the Keller-Box method. The investigation reveals the dependence of solute and nanoparticle concentrations, temperature, and velocity profiles on various parameters, with graphical analysis demonstrating their impact on the boundary layer characteristics. The study highlights the potential applications and innovations in industrial fields resulting from the analysis of Brownian motion and thermophoresis effects near the stagnation point in fluid flow, while also emphasizing the relevance of Buongiorno's model for enhancing heat transfers in double-diffusive fluids.

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.

Computational framework of hydrodynamic stagnation point flow of nanomaterials with natural convection configured by a heated stretching sheet

Bilal Ali et al.

Summary: The importance of convective heat transfer is intensified in various disciplines of modern engineering and technological development. This study focuses on developing a mathematical model for the 2D stagnation point flow of a heated stretchable sheet, considering nonlinear thermal radiation and a revised nanofluid model. Analysis includes the influence of Newtonian heating, MHD flow, and Brownian movement features. The nonlinear PDEs are modeled using boundary layer theory and converted into nonlinear ODEs using MATHEMATICA 11.0 programming. Graphical illustrations provide insights into the relevant flow parameters. This investigation greatly impacts engineering applications in geophysical and geothermal systems, storage devices, space science, and other disciplines.

Significance of entropy generation and nanoparticle aggregation on stagnation point flow of nanofluid over stretching sheet with inclined Lorentz force

Basim M. Makhdoum et al.

Summary: This study investigates the effect of nanoparticle aggregation on the thermal conductivity of nanofluids. Experimental measurements of velocity, temperature, and entropy production are performed with and without nanoparticle aggregation. The results show that nanoparticle aggregation improves the thermal conductivity and increases the velocity, temperature, and entropy generation.

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 suction with nanoparticles aggregation and joule heating on unsteady MHD stagnation point flow of nanofluids over horizontal cylinder

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.
