Abstract
The aim of this current contribution is to examine the rheological significance of Maxwell fluid configured between two isothermal stretching disks. The energy equation is also extended by evaluating the heat source and sink features. The governing partial differential equations (PDEs) are converted into the ordinary differential equations (ODEs) by using appropriate variables. An analytically-based technique is adopted to compute the series solution of the dimensionless flow problem. The convergence of this series solution is carefully ensured. The physical interpretation of important physical parameters like the Hartmann number, Prandtl number, Archimedes number, Eckert number, heat source/sink parameter and the activation energy parameter are presented for velocity, pressure and temperature profiles. The numerical values of different involved parameters for skin friction coefficient and local Nusselt number are expressed in tabular and graphical forms. Moreover, the significance of an important parameter, namely Frank-Kamenetskii, is presented both in tabular and graphical form. This particular study reveals that both axial and radial velocity components decrease by increasing the Frank–Kamenetskii number and stretching the ratio parameter. The pressure distribution is enhanced with an increasing Frank–Kamenetskii number and stretching ratio parameter. It is also observed that thetemperature distribution increases with the increasing Hartmann number, Eckert number and Archimedes number.

Summary
The mixed convection flow is the combination of both coupled free and forced convection, and is a topic of particular interest from an engineering (aerospace and chemical engineering) point of view in the past few years. Two-dimensional stagnation-point flow of upper-convected Maxwell fluid (UCM) over a stretching sheet has been determined by Hayat et al [16] They used the homotopy analysis method (HAM) to solve the resulting nonlinear differential equations. Discussed the effects of temperature-dependent viscosity, thermal conductivity and internal heat generation/absorption features in the MHD flow of upper-convected Maxwell fluid configured by a stretched surface. We study an incompressible mixed convection flow of Maxwell fluid between infinite isothermal stretching disks in the presence of heat absorption/generation, activation energy and chemical reaction features. The study of the mixed convection flow of non-Newtonian fluid encountered enormous applications in nuclear engineering, chemical engineering and petroleum industries. The considered flow problem contained the impact of activation energy, which includes diverse industrial and engineering significance, like oil emulsion, food processing, chemical processes and geothermal reservoirs. The problem is solved analytically via the homotopy analysis method, and the results are discussed through pictorial and tabular representations
