Abstract:
The present research describes the thermal radiation, viscous dissipation, and magneto porosity effects of unsteady combined magneto convective heat-mass transfer by a micropolar binary fluid mixture due to an inclined porous plate. Its findings could assist as a valuable guide in the specialized field of fluid dynamics, offering practical applications in food processing, aeronautical, missile, satellite, petroleum, hydrology, oil reservoir technology, agricultural engineering, gas turbines, solar power, cooling of electrical appliances, and the biomedical sector. In particular, magneto porosity has substantial consequences in the field of cellular cells. The governing partial differential equations are converted into ordinary differential equations by using similarity transformation before being solved numerically using the shooting technique and the implicit finite difference method (IFDM) with the help of MATLAB software and FORTRAN programming, respectively. The results for the velocity, temperature, concentration, and micro-rotation profiles and the thermo-physical quantities like local skin friction coefficient, local Nusselt number, local Sherwood number, and surface couple stress are presented for several values of the governing parameters obtained from both the shooting technique and the IFDM. The convergent figures are found for the higher values of thermal and solutal Grashof numbers and lower values of local magnetic field parameters. The temperature, micro-rotation, and velocity fields escalate with increasing Eckert numbers. The radiation parameter, Darcy number, and variable viscosity parameter increase the flow rate of the fluid. Increasing radiation parameters, suction parameters, and Prandtl numbers lessen the fluid temperature. Improving Eckert number, inclined angle, Schmidt number, Prandtl number, and magneto porosity parameter reduces the local skin friction. The heat transmission rate escalates in quantity due to larger Prandtl number values. Rising Prandtl, Eckert, and Schmidt numbers accelerate the mass transfer rate. The accuracy of the investigation is achieved by comparing the numerical outcomes with the published articles. Also, the numerical outcomes obtained from the shooting technique and the IFDM are compared for more accuracy in the study. Both of the qualitative and quantitative comparisons appear to be in good agreement. To determine whether the results are insensitive to the grid size, a new study grid independence test (GIT) is performed. The test shows that the findings of this study are uncaring of the grid sizes.
