“…Recently, Rubaa'i et al, [6] who studied the effect of non-uniform heat source/sink on the hybrid nanofluid mixed convection flow over a stretching sheet concluded the concentration of the chosen nanoparticles significantly contributed to the enhancement of heat transfer rate. Meanwhile, Low et al, [7] investigated the heat transfer characteristics of dusty nanofluid over a moving plate in the presence of MHD with convective boundary condition. The comparative analysis between copperoxide (CuO) and aluminium oxide (Al 2 O 3 ) -water dusty nanofluid showed that the increasing of the volume fraction of nanoparticles and volume fraction in dust particles significantly enhanced the temperature profiles of the flow.…”

Magnetic field involvement can influence heat absorption in electrically conducting fluid flow, which is useful in the control of features of final products in industries such as radiation therapy, aeronautics, and MHD generators. Consequently, this study investigates the effect of an aligned magnetic field on nanofluid flow over a stretching sheet with the boundary condition of Newtonian heating. Steady nanofluid flow with copper as chosen nanoparticles and water as conventional base fluid is considered. The problem is governed by a system of nonlinear boundary layer equations with appropriate boundary conditions which are then transformed into non-dimensionless equations using an appropriate similarity transformation. A numerical approach known as Keller-Box method is used to solve the transformed governing equations. The numerical solutions obtained are presented graphically in the form of velocity and temperature profiles for different values of aligned angle of magnetic field, Newtonian heating parameter, Prandtl number and nanoparticles volume fraction. A significant increase in aligned angle results in a decrease in fluid velocity, but an increase in temperature profile of nanofluid flow. The increment in the Newtonian heating parameter as well as the nanoparticle volume fraction also causes the temperature to increase.

“…In the study, dual solutions which are upper and lower solutions have been detected and successfully proven for certain range of mixed convection parameter. On the other hand, Low et al, [14] who explored the dusty nanofluid flow with the presence of magnetic field concluded that an increase in Biot number which represented the influence of convective boundary condition on the fluid flow has improved the flow temperature, consequently enhanced the heat transfer rate. They also observed that the magnetic field parameter has a tendency to create an opposing force to the flow, lowering the velocity boundary layer while increasing the heat boundary layer.…”

This study focuses on the investigation of nanofluid flow with convective boundary conditions past a static wedge by considering copper as the chosen nanoparticles and water as the conventional base fluid. The governing partial differential equations (PDE) are transformed into a set of nonlinear ordinary differential equations (ODE) by using an appropriate similarity transformation. The transformed governing equations are then solved numerically by using the Keller-box method. The significant impact of parameters included wedge angle parameter, mixed convection parameter, volume fraction of nanoparticle and Biot number are presented. The graphical analysis on velocity and temperature profiles revealed that the increasing values of all considered parameters causes the increment of velocity of the flow. Meanwhile, significant changes on the temperature profiles are clearly depicted on the increment of nanoparticle volume fraction as well as the Biot number.

The effects of viscous force on magnetohydrodynamic flow in coaxial cylinders are discussed in this article. The inner cylinder stretches linearly along the axis, while the outer cylinder rotates with some fixed angular velocity. The movement of the fluid between these concentric cylinders depends on the stretching of the inner cylinder and the outer cylinder's rotation. Understanding this type of flow is crucial for applications in engineering and industrial processes, such as magnetic materials processing and fluid transport in rotating machinery. The inner cylinder's surface is also considered slippery, that is, the first order slip condition is incorporated on the internal cylinder surface. The impact of viscous dissipation is also calculated in the current study. After using suitable transformations, we turn mass conservation, Navier‐stokes, and energy equations into dimensionless ordinary differential equations. Meanwhile, the numerical solutions of these equations are conducted via the shooting method. The numerical outcomes are graphically presented by varying the values of some certain parameters like the curvature parameter, the gap between the cylinders, the magnetic parameter, the slip parameter, and so forth. It is noted that the expanding gap size enhances the velocity of the fluid, accompanied by a rise in the fluid temperature. Additionally, the findings indicate that cylinders with a smaller gap exhibit a higher heat flux rate. The novelty of this work lies in the combined effects of viscous dissipation, slip conditions, and MHD on flow and heat transfer, offering insights beyond what has been previously explored in the literature.
