“…These fluids resemble rigid molecules, magnetic fluids, dusty clouds, muddy fluids, and biological fluids [5]. The problem of stagnation point flow in a micropolar fluid has been extended in numerous ways to include various physical effects [6][7][8][9][10][11][12][13][14][15].…”

This paper examines the magneto hydrodynamic (MHD), stagnation-point flow and heat transfer caused by an exponentially stretching/shrinking vertical sheet and the presence of mixed convection (buoyancy effect) in a micropolar fluid. A set of variables is employed to transform the system of partial differential equations (PDEs) to ordinary differential equations (ODEs). The ODEs are then numerically solved in MATLAB software using BVP4c. There are a lot of agreements when compared to previous findings. The impacts of different parameters, such as micropolar, magnetic, mixed convection, radiation, temperature, and stretching/shrinking parameters are displayed graphically. It is found that contradictory phenomena between Micropolar and mixed convection for fluid velocity, angular velocity and temperature distribution profiles. The velocity profile at the vertical plate increases due to the increasing buoyancy, magnetic and radiation parameters. The particle rotation occurs in two phenomena for buoyancy and magnetic parameters and it is reversible for micropolar. The temperature of the fluid decreases with buoyancy and magnetic parameters.

The purpose of the study is to discuss the comparison of the linear and nonlinear stretching sheets on the heat transfer over a curved surface spiraling in a circle with radial distance R. Additionally the consequences of Soret-Dufour in the presence of injection velocity and heat source/sink are investigated in the article.Silver and Copper Oxide are taken as hybrid nanoparticles with water as foundation fluid. Leading equations are converted to nonlinear ordinary differential equations taking some relevant transformations and solved with the combination of the shooting method and RK-4th order method. MAPLE software is used to plot graphs and numerical charts. Flow features are examined for different pertinent parameters. Physical quantities like Sherwood number, Nusselt number, and so forth, are evaluated numerically for different nondimensional numbers. The result substantiates that improving the Dufour number boost the fluid flow and fluid temperature but the opposite behavior is seen in the concentration profile. It is observed that a linearly stretching sheet gives better fluid behaviors compared to nonlinear stretching sheet.

“…Bakar and Soid [4] have investigated MHD micropolar fluid flow over an exponential vertically enlarging surface using the convective conditions. Abbas et al [5] studied arithmetically the time-dependent fluid flow and have revealed that growth in rotational and magnetic factors have upsurge the rotational motion of fluid. Gopal et al [6] revealed the impact of convective and buoyance forces over micropolar fluid flow upon a shrinking permeable sheet.…”

The industry level enhancement of the thermal conductivities of various base fluids is greatly aided by a nanofluid. Most engineering phenomena call for the removal of heat in order to improve industrial machinery performance. These fluids have a variety of uses, such as coolants for electric gadgets, car engines, heat exchangers and nuclear reactors. In this article, the authors have investigated the micropolar water‐based hybrid nanofluid containing silver and alumina nanoparticles over an extending surface. The flow problem also takes into account the Joule heating, variable heat source/sink, thermal radiation, chemical reaction, and activation energy. The flow problem is taken in the form of PDEs which are then transformed to ODEs by means of suitable similarity variables. The flow problem is solved with the help of HAM, which is capable of solving highly nonlinear partial and ordinary differential equations. The convergence of the HAM is also shown with the help of Figure 1. The results showed that the physical parameters have a greater influence on the velocity profile of nanofluid flow than hybrid nanofluid flow. However, the upshots of the physical constraints on the thermal profiles have a dominant impact on the hybrid nanoliquid flow relative to nanofluid. Also, it found that the physical parameters have a greater influence on the energy and mass transfer rates of the hybrid nanofluid flow than the nanofluid.
