Mixed Convection Magnetohydrodynamics Flow of Micro Polar Nanofluid Over Stretching Cylinder with Cattaneo-Christov Theory and Chemical Reaction

In this article,the present study examined the two-dimensional flow of micropolar nanofluid over a stretching cylinder with chemical reaction and the Cattaneo-Christov heat flux model. The Buongiorno’s nanofluid flow model is utilized to study the effects of thermophoresis and Brownian motion. The governing partial differential equations are modeled and reduced to ordinary differential equations by applying suitable similarity transformation, thereafter solved numerically through bvp4c technique in the MATLAB R2017b software. Accordingly, the numerical results reveal that velocity profile increases due to enhancement of solutal buoyancy, magnetic parameters, chemical reaction, thermophoresis, and thermal relaxation time. In a similar manner, micropolar fluid, curvature, Brownian motion chemical reaction and solutal relaxation time increases of causes on velocity profile to rise. The cylinder curvature ( λ ), micro-polar fluid effect ( Κ ), and micro-polar at the surface ( n ) parameters are enhanced that all contribute to the angular velocity profile’s rate of growth. The temperature profile of the nanofluid shows an increasing pattern in the following parameters: viscous dissipation, Brownian motion, micropolar factor, cylinder curvature, Prandtl number, and biot number. Moreover, the concentration profile decreases with increasing Prandtl number,relaxation time parameters, dissipation viscous factor, Schmidt number, magnetic, chemical reaction, and thermophoresis components other parameters effects on concentration are increases. The pair stress and skin friction coefficient decrease as a result of the impacts of the micropolar factor (K). The opposite result on Nusselt and Sherwood numbers as the cylinder curvature rises becomes of engineering interest. Finally, the results show an excellent degree of agreement when compared with the existing literature.
