Magneto-Oldroyd-B fluid flow over an exponentially accelerated vertical porous plate with heat source and reactive agents

Abstract

ABSTRACT The present research work describes about flowing magnetohydrodynamic generalized Oldroyd-B liquid model in an exponentially accelerated vertical porous boundless device with heat source and reacting species and heat source. The fully developed Oldroyd-B fluid model is stimulated by heat source/sink and species reaction and vertical device under the influence of gravity. The physical flow equation is modelled in the form of partial derivative which is mutated into the dimensionless partial derivative equations by invoking suitable non-dimensional variables. The partial system of derivative equations is tackled by employing perturbation technique. The outcomes for the velocity flow field, thermal and species distributions are exhibited graphically. Computed outcomes for the plate friction, heat gradient and Sherwood number are provided in table. Furthermore, correlation in terms of validation has been tabulated. Some obtained results show that an increase in heat source and time reduces velocity plots but increase the rate of particle temperature. Owing to the Lorentz force produced by the imposed magnetic field, the velocity alongside velocity degenerates. Time parameter compliments the fluid temperature, particle concentration and fluid transport. The heat transfer rate accelerates with higher Prandtl number and heat source, but mass transfer rate retards with higher Schmidt number.
