Implication of forced convective flow of nanofluid towards an exponentially stretched surface: Non-similar transformations

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 [Formula: see text] as non-similarity variable, and [Formula: see text] as pseudo-similarity variable along with appropriate transformations. Graphical analysis for various dimensionless numbers such as thermophoresis [Formula: see text], ratio of mass and heat transfer Grashof numbers [Formula: see text], Brownian motion [Formula: see text], buoyancy parameter [Formula: see text], Eckert number [Formula: see text] and Lewis number [Formula: see text] is presented using local non-similarity (LNS) via finite difference based algorithm bvp4c. A raised flow profile wasobserved with increasing [Formula: see text] and N. Boost in thermal profile was noticed for lager [Formula: see text] Increasing N and [Formula: see text] decreases the temperature profile. The concentration was a decreasing function of [Formula: see text] and N and increasing function of [Formula: see text]
