This research investigates steady, incompressible, magnetized micropolar fluid flow between two parallel plates in a rotating frame with homogeneous-heterogeneous reactions and suction/injection effects. Thermal analysis includes thermal radiation with temperature-dependent viscosity and thermal conductivity. To investigate this complex scenario, the fundamental equations of flow are transformed into a coupled system of non-similar, dimensionless equations using a local non-similarity transformation, accommodating variable fluid properties and rotation effects. The coupled equations are solved numerically by using bvp4c in MATLAB. The study thoroughly examines the effect of various physical evolving parameters on the velocity, microrotation, temperature, and concentration profiles. Notably, the velocity profiles exhibit a unique dual behavior between the two plates, indicating a complex flow pattern. The effects of the variable viscosity parameter show a decreasing trend near the lower plate. As the fluid moves toward the upper plate, the velocity changes its behavior. Moreover, the influence of variable thermal conductivity is found to enhance the fluid temperature in the rotating system. The novelty lies in combining variable properties, chemical reactions, and rotation in a non-similar micropolar flow analysis, with applications in rotating microfluidic devices and MEMS.
