Effects of aggregation kinetics on nanoscale colloidal solution inside a rotating channel

The objective of the present investigation is to reveal the effects of aggregation kinetics on the nanofluid flow between two revolving plates. Additionally, we have presumed that the upper surface of the revolving structure is permeable while the lower one is blessed to move with variable speed. Here we have introduced Nimonic 80A alloy nanoparticles with water as a base liquid. Aggregation kinetics at molecular level has been introduced mathematically to model our work and to explore how aggregation features affect the thermal integrity of the system. Similarity technique guided us to avail non-dimensional form of leading equations. RK-4 method along with shooting technique aids us to solve nonlinear ODEs. Several features of aggregation parameters on velocity and temperature profile have been explored through graphs and tables. Results extract that effective thermal conductivity of aggregated composite increases for nanoparticle volume fraction. Heat transport drops off for radius of gyration factor at lower segment but rises at upper regime.
