Abstract

This article focuses on the characteristics of the viscous fluid flow over a linear stretching sheet embedded in a porous medium. Cattaneo-Christov heat flux model is used instead of classic Fourier's law of heat conduction. Governing equations for the flow problem are reduced to nonlinear ordinary equations by applying suitable transformations. The impact of various pertinent parameters on the velocity, temperature, and concentration fields is analyzed through graphs. It is analyzed that higher thermal relaxation parameter results in the reduction of the temperature field. It is perceived that for increasing values of porosity parameter, velocity field increases.
