Abstract

Here formulation and computations are made to explore the characteristics of the boundary layer flow of a Burgers fluid in the presence of nanoparticles. Effects of thermal and concentration stratifications and heat generation/absorption are considered in the energy and concentration expressions. Meaningful transformations are employed to reduce the nonlinear partial differential equations into ordinary differential equations. Convergent solutions for arising nonlinear problems are obtained. Impacts of emerging physical parameters on velocity, temperature and concentration profiles are elaborated. Numerical values of local Nusselt and Sherwood numbers are tabulated and interpreted for different values of physical parameters.
