The present study analyzed micro-polar nanofluid in a rotating system between two parallel plates with electric and magnetic fields. The fluid flow study was performed in a steady state. The governing equations of the present issue are considered coupled and nonlinear equations with proper similar variables. Numerical and new semi-analytical methods have been employed to solve the problem to define the exactness of the results. The influence of physical parameters governing the problem is investigated and illustrated in detail in the diagram. Results show that velocity profile and micro-rotation velocity increased when the magnetic parameter increased. Furthermore, the velocity is increased by increasing the rotation parameter. Also, in the case of the temperature profile, the Reynolds and Schmidt number has an inverse effect, and Prandtl Number and Brownian motion have a direct effect. Other results indicate that concentration value declines by increasing the Thermophoretic parameter and Reynolds number. Results compare to the prior research display good accuracy and efficiency.
This study examined a rotating system by a micro-polar nanofluid between two parallel plates in the presence of magnetic and electric fields. The flow study has been performed in a steady-state. The governing equations of the present problem are transformed into nonlinear and coupled equations with appropriate similarity variables. The impacts of the Nusselt number, skin friction, and Sherwood number on temperature, velocity, and concentration distribution have been discussed. This research has mainly investigated the effects of the rotation, Brownian motion, thermophoresis analysis, and Hall current of micro-polar nanofluid. Results demonstrate for weak concentration [Formula: see text] and strong concentration [Formula: see text], that Nusselt number (Nu) increased with higher value of [Formula: see text], [Formula: see text] and decreased when [Formula: see text], Sc and [Formula: see text] increased. Also, by increasing the [Formula: see text] and Sc numbers, the temperature profile is decreased and increased by increasing [Formula: see text], [Formula: see text], and Pr. In addition, at a higher value of the [Formula: see text], the velocity profile in the [Formula: see text]-direction increased because of increasing the fluid motion and by fast ionization, increasing the [Formula: see text] parameter raised the velocity profile in the [Formula: see text]-direction. There was a decrease in the velocity profile in the [Formula: see text]-direction and the micro-rotation velocity profile. Our results show that the method used is very efficient and practical for solving this category of coupled equations, and that the solution of higher-order nonlinear differential equations in engineering is very consistent. Also, by comparing the obtained results with the previous results, the obtained values differ by about 6%.

in this study radiative micropolar nanofluid passed through a porous channel was analyzed. Because of the considerable amount of difference Finite element technique with approve of AGM was used. Different parameter and dimensionless numbers like Reynolds number Re, Hartman number M, thermophoretic number Nt with variation of velocity, temperature and concentration profile are shown graphically. There was no change in velocity or microrotation profile while there was a change in Reynolds number. Although concentration profile decreased with increasing of Reynolds number.
