Innovations in Eyring–Powell radiative nanofluid flow due to nonlinear stretching sheet with convective heat and mass conditions: Numerical study

ABSTRACT

The augmentation of heat and mass transfer in an industrial process due to convective boundary conditions plays an important role which cannot be ignored and the study lead to saving energy, reducing process time and increasing thermal rating. The impact of nonlinear thermal radiation on Eyring-Powell nanofluid flow over a nonlinear elongating sheet with Joule and viscous dissipation is investigated. The well-posed boundary layer problem is reduced into a highly nonlinear coupled ordinary differential system by adopting similarity transformations. The resultant equations subject to convective temperature and concentration conditions are then solved by employing a Runge-Kutta-Fehlberg 45 order numerical scheme combined with shooting technique. The flow characteristics affected by the pertinent parameters are calculated and presented through the graphs. It is witnessed that the increase in mass Biot number and Lewis number aggregates to rise in the Sherwood number. Also, the rate of heat transfer coefficient rises with growing values of thermal Biot number and radiation parameter. These investigations are of great importance in food processing, crystal growth, fibre and wire coating, production of glass fibres and in many possible areas.
