In this paper, the concept of microstructural slip is introduced in the flow of micropolar fluids pertinent to model various physical situations. The flow is modeled by a set of PDEs which are transformed to a nonlinear system of ODEs by employing boundary layer transformations. The system of governing equations is implemented using MATLAB bvp4c function along with the initial-boundary conditions. The code is validated by comparing the computed results in the limiting case with the available literature. Influence of microstructural slip on the skin friction coefficient and Nusselt number along with hydrodynamic and thermal boundary layer profiles is studied and discussed. It is found that, in the presence of microstructural slip, the microrotational velocity boundary layer thickness decreases up to a maximum of 37.5% in its value, in comparison to the case where there is no microstructural slip effect. The results predict that, in the presence of first-order translational slip, the microrotations have shown counterrotational phenomena in comparison to the case where there is no translational slip effect. Moreover, second-order translational slip results in declining the microrotational velocity and associated layer thickness.

“…In this paper, the three-dimensional rail welding model is proposed by combining Maxwell equations with the basic theory of the Fourier heat transfer equation [ 26 , 29 ], and a complete calculation method of a three-dimensional physical vector is designed. In other words, the changes of temperature, electric field, and magnetic induction intensity of some special points in the three-dimensional space position (A1–A4, B) on the rail are calculated.…”

“…The finite element numerical simulation method [ 24 , 25 ] is used for numerical simulation of the eddy current heat treatment process of the rail. The finite element differential equation in the mesh division is also established by taking into account the Maxwell equation [ 26 , 27 ] in electromagnetic theory and the Fourier heat transfer law [ 28 , 29 ] in the heat transfer theory. The numerical simulation results are analyzed by the magnetic induction and temperature changes of the U75V rail eddy current normalized heat treatment under different conditions.…”

In this paper is given a three-dimensional numerical simulation of the eddy current welding of rails where the longitudinal two directions are not ignored. In fact, usually it is considered a model where, in the two-dimensional numerical simulation of rail heat treatment, the longitudinal directions are ignored for the magnetic induction strength and temperature, and only the axial calculation is performed. Therefore, we propose the electromagnetic-thermal coupled three-dimensional model of eddy current welding. The induced eddy current heat is obtained by adding the z-axis spatial angle to the two-dimensional electromagnetic-thermal, thus obtaining some new results by coupling the numerical simulation and computations of the electric field and magnetic induction intensity of the three-dimensional model. Moreover, we have considered the objective function into a weak formulation. The three-dimensional model is then meshed by the finite element method. The electromagnetic-thermal coupling has been numerically computed, and the parametric dependence to the eddy current heating process has been fully studied. Through the numerical simulation with different current densities, frequencies, and distances, the most suitable heat treatment process of U75V rail is obtained.

Optimal control over heat transfer during the manufacturing of various significant cylindrical components is vital to achieving a desirable finished product. Insertion of various-shaped nanoparticles provides a promising solution to the problem at hand due to their greater thermal conductivity and unique features. Keeping in view, the present article is an effort to explore the slip flow of hydrogen-oxide [Formula: see text] infused with lamina- and column-shaped tungsten, tin, and titanium nanometer-sized particles over a nonlinear radially stretching surface. The physical model is presented by utilizing the fundamental laws of mass, momentum, and energy conservation. Magnetohydrodynamics, thermal radiation, and viscous dissipation effects are incorporated to provide physically realistic analysis. Utilizing scaling analysis flow governing problem is converted into a set of higher-order nonlinear Ordinary differential equation’s which afterward are tackled numerically. Quantities of practical significance such as surface friction and heat flux are portrayed through bar graphs and are examined physically in a detailed manner. Column shape tungsten nanoparticles offered minimum surface drag with the highest heat transfer rate compared to the other two particles making them an optimal choice in manufacturing cylindrical components as per our study.
