Abstract :The analysis of boundary layer thickness and temperature distribution effects in a viscous fluid flow of varying Hartmann intensity and thermal nonequilibrium over an exponentially extending/attenuation sheet is discussed in the current work. The fundamental issue involves recovering the ordinary differential models from the leading Navier-Stokes equations of conservation of momentum, energy, and mass which appear in partial differential forms through the similarity estimation approach. The recovered coupled ordinary differential equations (CODEs) have been analytically resolved using the series technique and evaluated numerically by employing the MATHEMATICA scheme. Furthermore, graphics discussion of the velocity, temperature, and concentration profiles are provided. Notedly, it is observed that as the Hartmann parameter Ht, improves, the drag, as well as the fluid velocity decreases. Also, enhancement of the thermal nonequilibrium number begets a rise in the temperature. On the other hand, as the threshold thermal Grashof number values appreciate, the skin friction is improved. Equally, the local Nusselt number declines due to enhancing the Prandtl and thermal nonequilibrium parameters respectively. Correspondingly, when the numerical values for the local Nusselt number, and coefficient of skin friction are compared to the literature that is currently available, they are found to be in close and total agreement.
