Impact of buoyancy on axisymmetric powell-eyring fluid with joule heating in presence of chemical reaction - Vol.34, Aug - Prayagraj Pushpa Publishing House 2023 - 65-91p.

The impact of buoyancy on axisymmetric radiative Powell-Eyring fluid flow towards a radially stretched surface is examined. To analyze the heat and mass transfer characteristics, thermal radiation, joule heating and chemical reactions are incorporated to the flow. The equations governing the fluid flow are obtained with the help of boundary layer approximation. The modeled coupled PDE system is transfigured as a system of ODE by exerting adequate similarity variables. Solution is represented in a numerical format by exerting Keller-Box method. A graphical representation is given to analyze the rheological nature of various parameters. A decent correlation is detected for present findings with the earlier outcomes. The increasing estimations of ε and Gr exhibit increment in velocity profiles. The increasing estimations of R and J exhibit increment in temperature profiles. The increasing estimations of kc exhibit increment in concentration profiles. An enhancement is detected in skin friction coefficient corresponding to the augmentation in ε, M and a drop is spotted by enhancing δ, Gr. Nusselt number rises by enhancing ε, Gr and also a decrement in Nusselt number by enhancing δ, M, R and J. An increment is detected in Sherwood number for rising values of ε, Gr and kc and a decrement is detected for rising values of δ and M.
