Summary: This study analyzes the flow of a two-dimensional incompressible magneto-hydrodynamic fluid on a linear stretching sheet in the presence of suction or injection and convective boundary conditions. The flow governing equations are solved using a scaling group transformation method and shooting technique. The computational results are validated and the effects of different parameters on friction and mass transfer rate are investigated.

Summary: Thermal radiation and thermophoretic particle deposition have important applications in research and engineering. This study investigates the movement of hybrid carbon nanotubes (CNTs) around a rotating sphere with the presence of thermal radiation and thermophoretic particle deposition. Nonlinear governing equations are converted into ordinary differential equations using similarity factors. Numerical results and graphical presentations are obtained using the Runge Kutta Fehlberg 45 order and a shooting approach. The study explores the impact of different limitations on the characteristics of the CNTs.

Summary: This article mainly focuses on the influence of chemical reaction slip condition on the unsteady three-dimensional Maxwell bio-convective nanomaterial liquid flow towards an exponentially expanding surface. The study examines the changes in temperature, velocity, microorganism, and concentration field through numerical calculations and graphical evaluation. The results show that the involvement of unsteadiness parameter restricts the transition from laminar to turbulent flow, while the velocity slip parameter has a decreasing effect on velocity components.

Summary: This study presents an analysis of an unsteady and incompressible flow of Williamson nanoliquid in the presence of variable thermal characteristics. By utilizing appropriate similarity variables, the equations for energy, momentum, and mass are converted into non-linear ODEs. The numerical solution of the boundary value problem is successfully implemented using a computer algorithm, confirming the accuracy of the results.

Summary: The study investigates the computational process of heat relocation analysis in a thin-film MHD flow embedded in hybrid nanoparticles. The effects of adsorption and injection on the hybrid nanofluid are discussed, and it is found that adsorption has a more significant impact. The presence of nanoparticles and magnetic field enhances the temperature distribution but reduces particle movement in the thin-film flow.

Summary: The thermal comfort of outdoor pedestrians is crucial for the quality of urban life. This study proposes a simulation method to investigate the thermal radiation experienced by pedestrians in street canyons. The results show that non-uniform thermal radiation is attributed to direct shortwave radiation, causing a temperature difference in different parts of the human body.

Summary: This paper investigates the stability of mixed convection of Al2O3/Water nanofluid in a horizontal porous channel with consideration of factors like magnetic field and thermal radiation. The effects of various parameters on flow stability, such as nanoparticle volume fraction and medium permeability, are analyzed. The results show that introducing nanoparticles into the base fluid increases fluid inertia and dampens disturbances. The shape of nanoparticles has an impact on flow stability, with blade-shaped particles having a more stabilizing effect. Oxide-type nanoparticles have a stronger stabilizing effect on small wave number disturbances compared to metallic-type nanoparticles.

Summary: This study numerically investigates the blood flow in a complex wavy curved channel in the presence of hybrid nanoparticles. The results reveal that the concentration of nanoparticles reduces the velocity of the blood and assists in the non-uniform channel core. Moreover, the volume fraction of nanoparticles and the dimensionless curvature of the channel decrease the temperature profile.

Summary: This article presents a numerical and statistical analysis of a novel thermal radiation and exponential space-based heat source on the bioconvective flow of a pseudoplastic 3D nanofluid past a bidirectional stretched Riga surface. The results show that nanofluids are more efficient in heat transfer and the flow profiles are influenced by various flow control parameters.

Summary: This study numerically explores the flow of hydromagnetic alumina-water nanoliquid due to a rotating rigid disk, considering different nanoparticle shapes and slip constraints. The modified Buongiorno model is used to model the flow, and the impact of parameters on physical quantities and flow profiles is explained. It is observed that temperature of the nanoliquid increases with hydrodynamic slip parameter and decreases with thermal slip parameter, with platelet-shaped alumina nanoparticles exhibiting the highest drag.
