Summary: The present study aims to predict the flow characteristics of a micropolar liquid infused with ternary nanoparticles across a stretching/shrinking surface under the impact of chemical reactions and radiation. The flow, heat and mass transfer characteristics are analyzed, including the suspension of three dissimilarly shaped nanoparticles (copper oxide, graphene, and copper nanotubes) in H2O. The governing equations are derived and transformed into ordinary differential equations for analysis. The impact of skin friction is also considered in this study, and the characteristics of the micropolar liquid are presented through graphs.

Summary: In this study, time-dependent, two-dimensional magnetohydrodynamic micropolar nanomaterial flow over a shrinking/stretching surface near the stagnant point is investigated with consideration of mass and heat transfer characteristics. The equations are solved numerically using a shooting scheme in MAPLE software, revealing dual solutions with different physical parameters. The stability analysis indicates that the first solution is stable and physically feasible, while the second solution is unstable and infeasible. Additionally, the impact of various physical factors on drag force, skin-friction factor, and mass and heat transfer rates is determined and interpreted.

Summary: The study investigates Magnetohydrodynamic micropolar fluid over a curved stretching surface using the Cattaneo-Christov theory of heat diffusion. A new heat model with relaxation time is employed instead of the classical Fourier theory, and curvilinear coordinates are utilized to model the governing equations. Nonlinear ODEs are solved using OHAM with BVPh2, showing how parameters affect the system.

Summary: This study addresses the flow of an incompressible, axi-symmetric and magnetized viscous fluid above a rotating disk. The disk can stretch or shrink along the radial direction. The flow governing equations consider the variable fluid features such as viscosity, thermal conductivity and mass diffusion. Two different cases of mass blowing/suction are considered, and the resulting flow model is solved numerically. The effects of different parameters on velocity, thermal and concentration fields are analyzed, and the Nusselt and Sherwood numbers as well as the skin-friction coefficient are calculated.

Summary: This study numerically investigates the stagnation point flow of a copper-water nanofluid across a convective stretching/shrinking cylinder, taking into account the effects of thermal radiation and viscous dissipation. The results demonstrate that for a shrinking cylinder, the skin friction increases while for a stretching cylinder, it decreases. On the other hand, the heat transfer rate exhibits the opposite trend.

The characteristics of heat and mass transfer are analyzed with thermal diffusion, heat generation, chemical reaction, and thermal radiation. The governing dimensionless equations are solved using the Laplace transform technique, and analytical expressions for velocity, temperature, and concentration are obtained. Effects of several pertinent parameters on velocity, temperature, and concentration distribution are presented graphically.

Summary: This paper investigates the mixed convection flow of a micropolar fluid in the presence of a magnetic field, with a non-linear stretching sheet through a porous medium. Non-uniform heat generation/absorption and chemical reaction are also taken into consideration. The governing equations are transformed using the similarity transformation and solved using the Homotopy Analysis Method. The effects of various parameters on velocity profiles, angular velocity profiles, temperature profiles, and concentration profiles are graphically presented. Skin friction, Nusselt number, and local Sherwood number coefficients are also determined and shown. The findings are in good agreement with earlier studies, revealing that thermal radiation parameter and material parameter enhance velocity and angular velocity profiles, Biot number and Eckert number significantly increase temperature profiles, chemical reaction parameter reduces concentration profile, and Soret number improves concentration profile. Heat transfer rate increases with thermal radiation parameter and decreases with Biot number for both linear and non-linear stretching.
