摘要

Inspired by the progressive relaxation characteristics of flow and its applied advantages in the rheological modeling of different dynamic fluids, the effect of multiple slip boundary conditions is one of the significant physical factors on the fluid flow analysis and has been considered in this study. The current article is focused on studying the heat and mass transference of MHD hybrid nanofluid flow on a rotating disk with viscous dissipation and chemical reactivity. Cattaneo–Christov flux model which accounts for finite speed of heat propagation is applied to consider the time relaxation effects. Furthermore, the thermal radiation and activation energy behavior have been used in this work. The proposed model has been solved by employing a semi-analytical approach HAM with Mathematica software. The physical aspects of the obtained numerical and graphical results are explained in detail to justify the required trend. From the result, it is inferred that the Eckert number (0.6–0.8) has an increasing behavior on temperature profile and heat transfer rate from (0.964104, 0.972517, and 0.983971), while the slip factor (0.2–0.5) has a declining influence on velocity, temperature, and concentration curve. Additionally, the thermal radiation parameter (0.6–0.8) enhanced the temperature and heat transfer rate from (0.671710, 0.689320, and 0.691347), and the activation energy factor (0.1–0.7) increased the concentration plot while the solutal relaxation time factor (0.2–0.6) decreased the mass transfer rate from (0.726624, 0.678307, and 0.635887). The findings from this analysis show that the heat from (5 to 16%) and mass transfer rates are higher for hybrid nanofluid as compared to nanofluid.
