Influence of Lorentz Force and Arrhenius Activation Energy on Radiative Bio-Convective Micropolar Nanofluid Flow with Melting Heat Transfer over a Stretching Surface

Novelty of this research is to explore an impact of Lorentz force, Arrhenius activation energy, and Conduction of Melting Heat on the micropolar fluid behaviour of steady radiative bio-convective micropolar nanofluid flow towards a stretchable surface. Using the standard similarity method, we have derived the equations of similarity for the relevant quantities of momentum, angular momentum, temperature, and concentration. The MATLAB tool 'bvp4c' is used to determine solutions to the transformed governing equations. Equations of similarity in four dimensions (momentum, angular momentum, temperature, and concentration) are numerically solved. We have examined, microrotation, velocity, concentration, temperature fields behavior for various parameters. Results show that the motile density of microorganisms decreases when the Peclet number and the microorganism concentration differential parameter are increased. Motility density increases as the Peclet number in microbial concentrations rises. Nanofluids are therefore appropriate as heat transfer fluids due to their surface cooling effect. The numerical scheme applied is validated by comparison with the previous numerical values.
