Significance of heat generation/absorption in magnetohydrodynamic flow by an unsteady stretching curved surface

Abstract

Purpose

The purpose of this article is to analyze the magnetohydrodynamic viscous liquid flow with heat absorption/generation. Flow is induced by an unsteady stretching curved surface. A time-dependent magnetic field is utilized.

Design/methodology/approach

The resulting nonlinear system is solved through shooting method.

Findings

An increment in the values of curvature A and unsteadiness parameters correspond to higher velocity, temperature and concentration fields. There is a reduction in the temperature and related layer via Prandtl number. Skin friction is increasing factor of magnetic number. Local Nusselt and Sherwood numbers are lower for greater magnetic number.

Originality/value

To the best of author's knowledge, no such consideration has been given in the literature yet.
