Abstract
Two-dimensional stagnation point flow of single and multi walls carbon nanotubes towards a stretching sheet is addressed. Induced magnetic field is considered. Homogeneous-heterogeneous reactions is accounted. Both SWCNTs (single wall) and MWCNTs (multi wall) are considered as nanoparticles whereas water and kerosene oil are considered as base liquid. Xue’s model is used for the physical characteristics of density, specific heat and thermal conductivity. The consequences of present work is to investigate impact of induced magnetic field in quartic chemical reactive stagnation point flow with influence of SWCNTs (single wall) and MWCNTs (multi wall). Dimensionless variables are introduced to model physical problem mathematically. Equations are then solved numerically with the help of Built-in-Shooting technique for non-dimensional induced magnetic field, velocity, concentration and temperature. The impacts of different dimensionless flow variables like stretching rate ratio parameter, magnetic parameter, thermal radiation, reciprocal magnetic Prandtl number, homogeneous reaction and heterogeneous reactions parameters and heat generation parameter are depicted through graphs. Computational analysis for surface drag force and Nusselt number are tabulated to examine the behaviors at stretched sheet. It is noticed that induced magnetic field enhances via higher nanoparticles volumetric fraction. Furthermore, multi (MWCNTs) has more contribution in enhancing induced magnetic field when compared with single (SWCNTs).
