The resulting governing partial differential equations are reduced into a system of nonlinear ordinary differential equations by employing similarity transformations, and then solved by means of the bvp4c solver. Dual solutions are found for certain intervals of the shrinking parameter, and suction is shown to increase solution stability by delaying the separation of the boundary layer. Comparatively, the local skin friction coefficient and Nusselt number for the ternary hybrid nanofluid are found to be higher than those of other fluids considered, showing better heat transfer performance. Moreover, optimization based on response surface methodology (RSM) shows that the local Nusselt number is maximized at low Eckert number, and high Biot number, radiation parameter, and magnetic parameter. The ternary hybrid nanofluid exhibits better heat transfer than the hybrid and base nanofluids at the optimum conditions<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p> <strong>Biography:<\/strong> <\/p>\n\n\n\n<p>Norihan Md Arifin is a Professor of Applied Mathematics at&nbsp;the Faculty&nbsp;of Science,&nbsp;Department of Mathematics and Statistics,&nbsp;Universiti Putra Malaysia (UPM).
