An analysis of effect of higher order endothermic/exothermic chemical reaction on magnetized casson hybrid nanofluid flow using fuzzy triangular number

In this study, we considered higher-order endothermic/exothermic chemical reactions with activation energy on Casson hybrid nanofluid flow (Fe3O4+Al2O3/C2H6O2) over a moving wedge under the fuzzy atmosphere, which includes the influence of thermal radiation, thermophoresis and Brownian diffusion. The main purpose of this analysis is to investigate the significance of fuzzy volume percentage on Casson hybrid nanofluid flow over a moving wedge. The transmuted nonlinear coupled fuzzy differential equations (FDEs) through the assistance of triangular fuzzy number (TFNs) are resolved employing numerical simulation of Runge-Kutta Fehlberg fourth-fifth order (RKF-45) along with shooting technique. The impact of the various physical parameters on heat and mass transfer are depicted in the form of graphs. The results demonstrate that an increase in solid volume fraction parameters (φFe3O4,φAl2O3), endothermic/exothermic reaction parameter (λ1), chemical reaction parameter (σ1), and temperature ratio parameter (δ) enhanced the rate of heat transport (Htx) of hybrid nanofluid. The rate of mass transport (Mtx) diminished by raising of Brownian motion parameter (Nb), Lewis number (Le), chemical reaction parameter (σ1), and temperature ratio parameter (δ). Also, for the comparison of nanofluid (Fe3O4/C2H6O2) and hybrid nanofluid (Fe3O4+Al2O3/C2H6O2) through membership function (MF), the solid volume fraction is taken as a TFN [0, 0.05, 0.1]. The MF and TNF are controlled by the α˜-cut, which has the range of [0, 1]. The fuzzy analysis indicates that the Fe3O4+Al2O3/C2H6O2 hybrid nanofluid provides a higher rate of heat transfer than Fe3O4/C2H6O2 nanofluids.
