Analysis of Newtonian heating and surface catalyzed reaction in a trihybrid nanofluid flow across an expanding/shrinking cylinder with Thompson and Troian slip

The objective of this study is to highlight the impact of Hall current combined with the surface-catalyzed reaction on trihybrid nanoliquid flow across a linearly expanding/shrinking cylinder in a porous media. The thermal endurance of trihybrid nanoliquid flow is assessed by integrating the modified Fourier law with Newtonian heating. Thompson and Troian slip condition is incorporated at the liquid-solid interface of the expanding/shrinking cylinder. The mathematical model is simplified with the inclusion of appropriate transformation. The bvp4c algorithm yields a numerical solution. The effect of various parameters on the flow distribution is illustrated through tables and graphs. Significant changes are noticed in the flow attributes of the trihybrid nanoliquid across a shrinking and extended cylinder. Higher values of the porosity parameter exhibit a decay and growth in the velocity of trihybrid nanoliquid flow for stretching/shrinking cylinder respectively. For large values of the Hall current parameter, fluid velocity delineates a decreasing trend for the shrinking cylinder and augments for the expanding cylinder. On enhancing the conjugate parameter for Newtonian heating, the thermal field boosts. The concentration field decelerates on augmenting the homogeneous reaction and surface-catalyzed parameters. An elevation in the drag force is noticed versus curvature and porosity parameters. Heat flux accelerates on incrementing the conjugate parameter over a shrinking and stretching cylinder. The present investigation is authenticated when the outcomes of the analysis are assessed with prior published studies. An intriguing correlation is noticed which affirms the consistency and precision of the flow model.
