Numerical analysis of the chemically reactive EMHD flow of a nanofluid past a bi-directional Riga plate influenced by velocity slips and convective boundary conditions

This report presents the three-dimensional electromagnetohydrodynamic fow of a zinc-oxide– water nanofuid past a bidirectional Riga plate with velocity slips and thermal and mass convection conditions. The Cattaneo–Christov heat and mas fux model, thermal radiation, chemical reaction and activation energy are considered to analyze the fow problem. The volume fraction of the ZnO nanoparticles is taken 6% in this analysis. An appropriate set of similarity variables is used to transform the partial diferential equations into ordinary diferential equations. During this process, some parameters are found and infuences of these factors on the fow profles are shown and discussed in detail. A numerical technique called NDSolve is considered for the solution of the nanofuid fow problem. The results showed that higher solid volume fraction and slip parameter have reduced velocities profles and the increasing solid volume fraction and thermal Biot number have increased the temperature profle. Additionally, the concentration Biot number has increased the concentration profle. The modifed Hartmann number has signifcantly increased the velocity profle. Dual impacts in velocity profles along primary and secondary direction has been observed due to stretching ratio parameter. A comparison of current results has been carried with a fne agreement amongst current and established results.
