Simultaneous features of MHD and radiation effects on the UCM viscoelastic fluid through a porous medium with slip conditions

In this article, we analyzed upper-convected Maxwell (UCM) viscoelastic fluid flow in a perme-able medium. Cattaneo-Christov (CC) heat flux theory is utilized for heat transfer phenomena. Impacts of thermal radiation, thermal slip condition and magnetohydrodynamic (MHD) are con -sidered in modeling of the physical phenomena under investigation. The developed equations of fluid flow model are transformed to non-linear ordinary differential equations (ODEs) with some suitable similarity transformations. Numerical solution of ODEs with boundary conditions are investigated and the results are depicted through graphs and analyzed accordingly. From the present results, we concluded that velocity is declining for magnetic parameter; temperature is rising with thermal radiation and magnetic parameters while it shows reducing behavior for thermal slip parameter. Nusselt number observes decreasing behavior for larger values of porosity parameter, magnetic parameter, Deborah number, velocity slip and thermal slip parameters while opposite behavior is seen for radiation and thermal relaxation parameters. Furthermore, the accuracy of the current data was determined by comparing the heat transfer rate for several values of the porosity parameter to previously published results.

Automated summary

In this article, the flow of upper-convected Maxwell (UCM) viscoelastic fluid in a permeable medium is analyzed. The Cattaneo-Christov (CC) heat flux theory is used for heat transfer phenomena. Various factors such as thermal radiation, thermal slip condition, and magnetohydrodynamic (MHD) are considered in modeling the physical phenomena. The equations of fluid flow are transformed to non-linear ordinary differential equations (ODEs) and solved numerically with boundary conditions. Results show that velocity decreases with the magnetic parameter, temperature increases with thermal radiation and magnetic parameters, and Nusselt number behaves oppositely for different parameters.
