Abstract

PurposeThe purpose of this paper is to examine outcome of activation energy in rotating flow of an Oldroyd-B nano liquid.Design/methodology/approachFlow is generated due to stretched surface. Binary chemical reaction is studied. Brownian and thermophoresis effects are considered. The system of nonlinear ordinary differential equations is derived. Convergent series solutions are obtained by homotopy analysis method. The resulting expressions for velocities, temperature and concentration are computed for different embedded parameters.FindingsIt is found that velocities f′ and g  have decreasing effect when rotation parameter is enhanced. Brownian and thermophoresis are increasing functions of temperature and concentration. The physical quantities are sketched and discussed numerically. Concentration and temperature fields show decreasing behavior via Brownian and thermophoresis parameters.Originality/valueAuthors investigate the Rotating flow of Oldroyd-B nano fluid with chemical reactions.
