Magnetohydrodynamic alumina–silver viscoelastic hybrid nanofluid flow over a circular stretched cylinder with nonlinear heat radiation and Arrhenius energy.

The present study is aimed at inspecting magnetohydrodynamic (MHD) viscoelastic hybrid nanofluid flow over circular stretched cylinder. We consider here alumina and silver as nanoparticles with base fluid carboxymethyl cellulose solution. The effect of heat source, heat radiation, and activation energy are taken into account. Moreover, with small Reynolds number, the induced magnetic field has no noticeable effect. The leading dimensional equations are converted to dimension-free form by employing similarity transformations. The converted equations are calculated by using MATLAB bvp4c numerical method. Graphs and tables are used to analyze velocity, skin friction, temperature, heat-mass transport rate, and concentration for numerous physical factors. Observation reflects that viscoelastic and curvature parameters enhance velocity profile. Moreover, heat source enhances fluid temperature. It is clearly reflected that volume fraction parameter for alumina and silver enhances the heat transport’s rate. The mass transport’s rate reduces for Arrhenius energy parameter. The present work compares to prior work without considering the newly added effects and finds consistent findings. [ABSTRACT FROM AUTHOR]
