Summary: This study focuses on the application of magnetized hybrid nanofluid in engineering and advanced industrial processes, and investigates the effect of suspended nano-size particles on the fluid flow using buoyancy and viscous dissipation. A numerical model of three-dimensional hybrid nanofluid flow is developed, considering the heat transmission phenomenon and the influence of parameters such as magnetic parameter M, slip parameter K, rotation parameter λ, and buoyancy parameter λb. The velocity and temperature distributions are determined using the Runge-Kutta (4th order) method, and the influence of various parameters on the flow behavior is graphically presented. The results are validated numerically and will contribute significantly to the field of fluid mechanics.

Summary: Nanofluids are a new generation of fluids that improve the heat transfer capabilities of conventional fluids. However, current nanofluid models fail to describe fluids with certain microscopic characteristics. This study numerically investigates the laminar two-dimensional heat transfer flow of a micropolar nanofluid containing copper nanoparticles and water through a porous medium over a stretching sheet. The effects of parameters such as micro-rotation, boundary, and suction on velocity, angular velocity, and temperature are analyzed.

Summary: Compared to Newtonian fluids, non-Newtonian fluids exhibit fascinating characteristics in heat transportation, especially in the context of nanoliquid flow over a revolving disk. The presence of gyrotactic microorganisms enhances the behavior of nanoparticles. This study considers various factors such as activation energy, thermal radiative effects, heated convective conditions, and entropy minimization to build a comprehensive model. The numerical solution of the resulting nonlinear ODEs provides insights into the influence of different parameters on the flow behavior.

Summary: This article discusses the two-dimensional steady laminar boundary layer flow and heat mass transfer caused by a non-Newtonian nanofluid due to a horizontally stretching sheet. By considering various non-dimensional parameters, including convective boundary condition, slip velocity, Brownian motion, thermophoresis and viscous dissipation, numerical values for dimensionless velocity, temperature and nanoparticle concentration are obtained. The distributions of these variables are plotted against important governing factors, and local skin-friction coefficient, Sherwood number and Nusselt number are discussed to further explain the problem.

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.

Summary: This study examines the numerical analysis of unsteady radiative and viscous dissipative fluid flow on a semi-infinite oscillating vertical plate. The effects of physical parameters such as velocity, concentration, temperature, skin friction, Nusselt number, and Sherwood number profiles on the flow pattern are portrayed and conveyed pictorially based on computational solutions. Surprisingly, plate oscillation, radiation, and viscous dissipation parameters greatly influence the flow pattern.

Summary: Thermophoresis and Brownian motion occur simultaneously in many industrial processes and have engineering significance. Mathematical models are used to investigate their dynamics, and numerical solutions are computed using the finite element method. Thermophoresis has increasing effects on concentration profiles, while the Brownian motion parameter has a decreasing impact. Brownian motion also plays a significant role in controlling the thickness of concentration boundary layers.
