It is a fact that adding nanoparticles to the base fluid increases its thermal conductivity. However, engineers encounter one big hurdle when they try to understand how internal molecular interactions like shapes and aggregation kinetics influence the fluid’s thermal physical characteristics. Because of this, the aggregation kinematics of nanoparticles becomes essential for determining the suitable thermal effect of particles at the nanoscale. So, the focus of this study is to examine the characteristics of nanoparticle aggregation and its influences on the micropolar nanofluid flow past a Riga plate. Additionally, the influence of non-Darcy effects, non-uniform heat source/sink, and Navier slip effect are also considered in this study. Under these assumptions, the governing is formulated and altered to the ordinary differential equation. Numerical solutions are obtained using inbuilt function bvp4c in MATLAB software, and outcomes are graphically depicted to study the impact of pertinent parameters on the flow field. We observed that nanoparticle aggregation significantly enhances the temperature field and diminishes the velocity field. Also, the source/sink parameter upsurges the temperature distribution, and the modified Hartmann number enhances the velocity profile. This study will be useful for real-world fluid flow problems like blood, exotic lubricants, additive suspensions, liquid crystals, and polymeric fluids through microchannels and capillaries.
