Soret and Dufour effects on Sutterby nanofluid flow over a Riga stretching surface with variable thermal conductivity

This research investigated the impact of Sorret and Dufour on the flow of Sutterby nanofluid over a stretchable Riga sheet while considering the variable thermal conductivity. The analysis was based on the Buongiorno nanofluid model, and nonlinear partial differential equations were formulated using the governing laws and applying the boundary layer approximations. These equations were transformed into ordinary differential equations using appropriate similarity variables. The bvp4c numerical scheme in MATLAB was used to calculate numerical and graphical results. The figures show how various parameters affect the velocity, temperature, and concentration profiles. Additionally, numerical results of the skin friction, Nusselt number, and Sherwood number for various parameters were presented in tables. The velocity distribution profile decreases with an increase in the Sutterby fluid parameter value but increases with the modified Hartmann number. The temperature profile rises with increased Dufour number and thermal conductivity. The concentration profile decreases with an increase in the Schmidt number and chemical reaction but increases with an increase in the Soret number.
