Abstract

In this work, a modified model for heat and mass transfer of mixed convection nanofluid flow over a stretching sheet is investigated. The model is described in form of partial differential equations (PDEs) and further, it is reduced to a dimensionless system of nonlinear PDEs. The main feature of the current study is to employ a non-similarity method that can be used for non-similar problems. The coupled ordinary differential equations are tackled by the MATLAB built-in solver bvp4c. The graphs for velocity, temperature, and concentration profiles are obtained with varying dimensionless parameters. Also, numerical values for quantities of physical interest skin friction coefficient, local Nusselt number and local Sherwood number are given through tables. By considering the effects of variable viscosity, an increase in velocity profile is found for growing values of the Grashof number.
