On the hydromagnetic reaction of Oldroyd 8-constant Arrhenius exothermic fluid and explosion slice-chain in a plane Couette

Abstract

A theoretical study of hydromagnetic reaction of Oldroyd 8-constant exothermic liquid and explosion bifurcation slice is examined. The temperature distribution of the reactive molecular diffusion of the non-Newtonian liquid takes place in a plane bounded Couette. Without displacement of currents and material consumption, the viscoelastic fluid is completely exothermic with low thermal equilibrium. The dynamical flow momentum is not stimulated by the species reaction, but by the chain branched order, Arrhenius generalized kinetics, initiation rate and the flow medium upper plate motion. The nonlinear exothermic reaction differential model is completely solved by adopting a consistent and convergent collocation weighted residual analytical procedure. The qualitative results in graphs and tables are presented for the flow dynamic, heat propagation and ignition bifurcation slice. The results revealed that the viscoelastic property of the material is augmented by an increasing magnetic term. Also, exothermic heat diffusion is enhanced by initiation rate and reaction exponential factor. Hence, heat generation terms must be controlled to prevent thermal science and engineering devices from blowup.
