1. Introduction
There are several models that have been proposed to predict the non-Newtonian behavior of various types of materials in the past few ages. The non-Newtonian fluids have been studied extensively because of their significant applications in different fields. Ketchup, toothpaste, shampoo, paint and blood are some of the examples of non-Newtonian fluids from our daily life. Among the many non-Newtonian fluid models, a model which has both properties of elasticity and viscosity was proposed by James Clerk Maxwell in 1867 and named as Maxwell fluid (Jordana et al. , 2004). Many researchers have examined this fluid model, the three dimensional steady of hydromagnetic flow of Maxwell fluid over bidirectional stretching surface with two different cases (prescribed surface temperature and prescribed surface heat flux) was considered by Shehzad et al. (2013). Hayat et al. (1991) stimulated the three dimensional MHD Maxwell flow with variable thermal conductivity in presence of heat source and sink. Series solution of mixed convection radiative flow of Maxwell fluid over an inclined stretching sheet with thermophoresis and convective condition was derived by Ashraf et al. (2015). Jamil and Fetecau (2010) obtained the exact solution of helical flows of Maxwell fluid subjected to accelerated shear stress. A comprehensive study regarding stability analysis of double-diffusive convection of Maxwell fluid was carried out by Wang and Tan (2008).
Flow between or over a rotating disk is an influential topic and popular among new researchers due to its meaningful applications in engineering. Von Kármán (1921) was the first who introduced the rotating disk model in 1921. The rotating disk flow constitutes a fundamental problem of interest in helicopter rotor aerodynamics, rotational viscometer, rotating machinery, magnetic energy propulsion systems, chemical engineering, spin-coating, centrifugal pumps and many others. Many calculations have been made on the rotating disk model of Kármán. Cochran (1934) studied the asymptotic solution for steady hydrodynamic flow over a rotating disk. Shahmohammadi et al. (2012) presented a steady flow and heat transfer from a rotating disk in a high permeability media. An analytical solution of 3D Navier-Stokes equations of flow near a rotating disk is obtained by Rashidi and Shahmohammadi (2009). Hayat and Nawaz (2011) discussed the unsteady stagnation point flow over a rotating disk. Ariel (1996) investigated the flow near the...
