Abstract

Purpose

The purpose of this study is to elaborate mixed convection impact in stratified nanofluid flow by convectively heated moving surface. Rheological relations of second-grade fluid are used for formulation. Magnetic field, heat absorption/generation and convective conditions are considered for modeling.

Design/methodology/approach

Convergent solutions are achieved using homotopy procedure.

Findings

The authors found opposing behavior for radiation and thermal stratification variables against thermal field.

Originality/value

No such analysis has yet been reported.
