Computational analysis for radiative rheological two-phase nanofluid flow, heat and mass transfer characteristics with velocity slip and chemical reaction effects

Abstract

In this study, we have considered steady-state, incompressible, 2D boundary-layer flow of a Buongiorno nanofluid model over a semi-infinite vertical sheet, examining the combined influence of MHD, thermal radiation, chemical reaction, and velocity slip. The governing equations, derived from the conservation laws of mass, momentum, energy, and species concentration, are reduced to a system of nonlinear ordinary differential equations through the application of non-similarity transformations with the Keller box approach. This reliable finite-difference scheme works well for boundary-layer problems, which accommodate the complexities inherent in the relationships among the variables involved. The impact of many important factors on the velocity, temperature, and concentration profiles of nanoparticles is thoroughly examined. Results reveal that velocity slip significantly reduces the fluid velocity near the wall, while thermal radiation enhances heat transfer rates. Furthermore, chemical reaction effects suppress nanoparticle concentration within the boundary layer. This research presents a novel integration of Buongiorno’s nanofluid model with the combined effects that have not been extensively explored together in prior studies. Additionally, an excellent agreement is achieved when compared with the latest published literature. The findings contribute to a deeper understanding of non-Newtonian fluid behavior and theoretical understanding of nanofluid dynamics over a semi-infinite sheet, and offer guidance for the design of efficient thermal systems and chemical processing technologies.
