Chemical Reaction and Radiation Effects on MHD Flow of Oldroyd-B Fluid through Porous Medium Past an Exponentially Stretching Sheet with Heat Sink

In this article, the effect of electromagnetic force with chemical and thermal radiation on Oldroyd-B fluid past an exponentially stretched sheet a heat sink porous medium was studied. The governing system nonlinear partial differential equations has transformed into ordinary using similarity transformations. is then solved numerically successive linearization method. numerical results velocity, temperature, concentration profiles are represented graphically. Several parameters’ effects investigated examined. Local Nusselt number, skin friction coefficient, porosity, Deborah numbers, local Sherwood number values listed analyzed. reveal that many parameters have significant impact flow profiles. were considerably affected by reaction rate parameter, thickness boundary layer decreased as parameter increased. analysis compared to existing works found be in excellent agreement.
