Abstract : It is well-known that adding a certain quantity of nanoparticles enhances the thermal conductivity of the nanoliquid. The reason for this tremendous improvement is yet unknown. Consequently, finding the appropriate thermal effect of particles at the nanoscale requires an understanding of nanoparticle aggregation kinematics. The influence of homogeneous and heterogeneous chemical reactions on an electrically conducting three-dimensional stream of Titanium dioxide– and ethylene glycol–based nanofluid through a stretching sheet with NP aggregation is investigated in this work. The modelling equations are converted into a system of ordinary differential equations (ODEs) using similarity transformations. These ODEs are numerically solved using the Runge–Kutta–Fehlberg fourth fifth-order (RKF 45) method and the shooting approach. Graphical representations are used to investigate and address the impact of essential factors on flow, thermal, and concentration fields along with skin friction and heat transfer rate. The results show that the fluid flow in the absence of NPs aggregation has better heat transport when the melting parameter increases. Furthermore, rising values of strength of heterogeneous and homogeneous reaction parameters result in improved mass transfer for fluid flow in the presence of aggregation conditions.
