Abstract

This investigation presents the heat and mass transfer phenomenon for the chemically reactive flow of second grade fluid subject to the homogeneous and heterogeneous (HH) chemical reactions. The viscosity of fluid is assumed to be temperature dependent instead of constant. The motivations for considering the viscosity as a function of temperature is justified with applications of metallurgical process, crude oil extraction, geothermal systems and machinery lubrication. Additionally, viscous dissipation and temperature dependent heat generation and absorption effects are also introduced to improve the thermal transportation phenomenon. The interaction of different new variables facilitates the problem into dimensionless form. The numerical achievements are predicted with implementing the Runge Kutta (RK4) method. The physical onset behind the parameters have been reported. The tabular quantitative analysis is performed for different physical quantities.
