Slip and radiative effect on magnetized CNTs/[formula omitted] hybrid base nanofluid over exponentially shrinking surface

Abstract

In current research, the physical characteristics of the laminar steady boundary layer flow of CNTs/ C2H6O2+H2O hybrid base nanofluid across a permeable exponentially contracting surface along the influence of magnetic force, heat radiation, and velocity slip of the first order have been examined. The effect of magnetic field stability analysis on the hybrid-based nanofluid flow of CNTs with thermal radiation was not previously explored for the numerous solutions, which is the originality of the current work. The partial differential equations (PDEs) controlling the model were transformed to ordinary differential equations (ODEs), and then the ODEs were solved using the three-stage Lobatto IIIa numerical approach in the MATLAB program. For different nanofluids constituted of SWCNTs and MWCNTs as nanoparticles and C2H6O2+H2O as the hybrid base nanofluid, the impacts of changes in the values of various parameters on temperature, velocity, heat transfer, and skin friction coefficient profiles were explored. Tables and figures illustrate numerically and quantitatively the outcomes. In addition to the effects of outputs, there are two solutions within the range of suction parameter. In addition, the parameter ∅ has a diminishing influence on heat transfer rate and skin friction coefficient in the first solution, resulting in a decrease in the surface drag force and heat transfer rate. Moreover, the selection of nanoparticle kinds has a substantial effect on the cooling/heating processes and stream function. Finally, a linear temporal stability analysis was performed to classify the stable solution among the dual solutions.
