Thermal and solutal transport analysis in swirling flow of Maxwell fluid subject to Cattaneo–Christov theory

Abstract

In this article, the thermal and solutal analysis are carried out in the swirling flow of Maxwell fluid over a stretchable rotating cylinder in the perspective of Cattaneo–Christov double diffusion theory instead of classical Fourier’s and Fick’s law for heat and mass transport phenomena. The constant rotation of the cylinder and axial-dependent stretching produced the flow under the influence of the magnetic field. The heat sink/source and chemical reaction in flow work as a controlling agent for energy transportation. The problem of thermal and solutal transport in flow under certain suppositions is modeled in the form of partial differential equations. Furthermore, the partial differential equations are converted to ordinary differential equations using flow similarities. To calculate the numerical computation of similar ordinary differential equations is performed through the bvp4c MATLAB technique. The flow phenomenon and energy distribution in flow are examined by using graphs. The key findings of this study reveal that increase in relaxation time parameters for heat and mass transport, both temperature and concentration profiles decline. Moreover, the energy transport increases for the higher heat source and chemical reaction parameters.
