Abstract

Abstract: Importance of heat and mass transmission is intensified remarkably in many engineering and technological process such as air conditioning, equipment power collectors, damage of crops, food processing, heat exchangers, refrigeration and many more. Main focus of this exploration is to disclose a mathematical modeling of chemically reactive Maxwell nanofluid for axisymmetric flow case by considering Cattaneo-Christov heat flux model and revised nanofluid model. Additionally, Arrhenius activation energy and magnetic field aspects are invoked. Furthermore, heat source/sink and nonlinear radiation repercussions are accounted. The essential partial differential equations of this exploration are modeled with the assistance of boundary layer estimation and then reconstructed into nonlinear ordinary differential equations by invoking proper transformation. Runge-Kutta-Fehlberg scheme is deployed to establish numerical solutions of this inspection. It is interesting to reveal that fluid temperature and associated boundary layer thickness grow due to enhancement of temperature ratio parameter and heat source parameter. Additionally, higher estimation of magnetic parameter and radiation parameter reflect in the depreciation of wall heat transfer. Furthermore, nanoparticle concentration is denigrated for exalting values of reaction rate parameter. For the endorsement of this communication, a comparison assessment is established with existing investigation and disseminated in excellent resemblance.
