Exploring the Combined Effects of Chemical Reactions and Thermal Radiation on Micropolar Nanofluid Flow Through a Riga Sensor Surface

The integration of electrodes and permanent magnets in the Riga plate induces a wall-parallel Lorentz force under external electromagnetic fields, ensuring advanced control of fluid flow. This work explores the flow properties of micropolar nanofluid flow over a porous Riga surface under the significance of chemical reaction. Furthermore, the combined effect caused by Brownian diffusion and thermophoresis with thermal radiation enriches the flow mechanism in the presence of convective conditions. The Runge-Kutta scheme of order four, along with the shooting method, is used to examine the characteristics of the flow field, followed by the suitable transformation utilized in the conversion process of the dimensional governing equation to its corresponding non-dimensional form. The detailed parametric investigation is carried out to examine the effect of various parameters on flow characteristics, and the corresponding results are displayed graphically. Lastly, the finding indicates that the thermophoretic and radiation parameters play a significant role in promoting surface temperature. However, both the chemical reaction and Schmidt number have a greater impact on slowing down the particle concentration profile.
