Abstract
This article presents the numerical scrutiny of the non-similar model of mixed convective flow of nanofluid initiated by an exponentially expanding sheet. Equations are modeled and transformed into non-dimensional partial differential system (PDE's) by defining dimensionless xi(x) as non-similarity variable, and eta (x ,y) as pseudo-similarity variable along with appropriate transformations. Graphical analysis for various dimensionless numbers such as thermophoresis (N-t) , ratio of mass and heat transfer Grashof numbers (N), Brownian motion (N-b) , buoyancy parameter (lambda) , Eckert number (Ec) and Lewis number (Le) is presented using local non-similarity (LNS) via finite difference based algorithm bvp4c. A raised flow profile wasobserved with increasing lambda and N. Boost in thermal profile was noticed for lager N-b . Increasing N and xi decreases the temperature profile. The concentration was a decreasing function of N-b , Le and N and increasing function of N-b .
