Three-dimensional unsteady flow of Maxwell fluid with homogeneous–heterogeneous reactions and Cattaneo–Christov heat flux

This article addresses the unsteady three-dimensional flow of Maxwell fluid. Flow is induced by a bidirectional stretching surface. Fluid fills the porous space. Thermal relaxation time is examined using Cattaneo–Christov heat flux. Homogeneous–heterogeneous reactions are also considered. Suitable transformations are used to convert partial differential equations into nonlinear ordinary differential equations. Convergent series solutions are obtained. Effects of appropriate parameters on the velocity, temperature and concentration fields are examined. It is found that increasing value of Deborah number decreases the fluid flow. Larger values of strength of homogeneous reaction parameter decrease the concentration distribution. Also temperature is decreasing function of thermal relaxation time. Present problem is of great interest in biomedical, industrial and engineering applications like food processing, clay coatings, hydrometallurgical industry, fog formation and dispersion.
