Von Kármán swirling analysis for modeling Oldroyd-B nanofluid considering cubic autocatalysis

Abstract Characteristics of von Kármán swirling flow for Oldroyd-B nanofluid in presence of heat absorption/generation are elaborated in this work. Analysis for nonlinear phenomenon have been prepared by considering convectively heated surface. More specifically, thermophoretic deposition and Brownian moment aspects in addition to chemical processes are considered in the mathematical modeling. Non-dimensionalization procedure is adopted by introducing apposite variables. Homotopy algorithm is opted for nonlinear analysis. Graphical analysis is prepared to portray the features of distinct variables against dimensionless quantities. It is noted that heat-mass transport mechanisms for von Kármán swirling flow significantly affect rate of heat-mass transport mechanisms. Additionally, graphical outcome of β 1 reveals that velocity of Oldroyd-B nanofluid deteriorates for larger β 1 . Moreover, we found assisting behavior of β 2 for velocity of nanofluid.
